How long do body cells live. How long do body cells live The last 30 years of life in a cell
Loving yourself and feeling comfortable in your body is especially important at 30, as decisions at this age have many consequences. But you can truly love yourself only when you begin to love your surroundings and in personal life, and at work. In addition, when you accept yourself as you are, there is a feeling of incredible freedom.
Start each day by welcoming and appreciating yourself, saying that you are smart, beautiful, talented and give your best. Be proud and confident in your choice, your likes and dislikes, hopes and dreams. And stop surrounding yourself with people who don't make you better. Spend time with loved ones and people who make you feel better. This will teach you to control emotions and increase self-esteem.
2. Take care of your personal life
Happiness, success, joy largely depend on how your personal life develops. So if you want to get married, have kids, or buy a house, 30 is the right time to reach those goals. Ask yourself what you can do in a year from now to build the love life you want. And don't hesitate. Save family life or children is imprudent. If you want kids, have them now before it's too late.
Blogger Mark Manson had the right idea about this:
You do not have time. You do not have money. First you need to build a career. They are the end of your measured life ... Oh, shut up already. Children are great. They make you better. They make you happier. Don't put them off until later.
Mark Manson
3. Do a job you really enjoy
Thirty years is also a great time to explore other areas, change occupations and improve in your real passion, whether it be music, writing or business. There is nothing worse than putting down roots on, forcing yourself to live such a life and not being able to follow true passion. This situation can be described economic term sunk cost, when you have to keep investing in something because you have already invested too much in it. It is the cause of many failed careers, failed businesses and many unhappy lives.
Find a job that you really love, where your desires match your skills, where you will get the most return.
Once said:
Your work will fill most of your life, and the only way to be completely satisfied - to do what you think is a great thing. And the only way to do great things is to love what you do.
Steve Jobs
4. Stop comparing yourself to others
Stop comparing yourself to others. We are all different and we all move at different speeds. This is important, because after the turn of 30 it is easy to get depressed and turn off the right path to happiness. Everyone knows that if you compare yourself to others, you can earn stress, and all your self-confidence will fly into the pipe.
Love yourself and keep taking care of yourself. Allow yourself to go your own way in life. “If you live differently than your family and friends, without comparing yourself to them,” says Kay Mahesh, “don’t be hard on yourself.”
5. Be happy with what you have
Instead of being angry and envious of others, be calm, benevolent, and content with what you have. Research shows that when you appreciate what you have, a feeling of happiness appears and negative emotions go away. Of course, we need to strive for the best, but it is important to understand that life does not always develop in accordance with our plans. This knowledge will protect against negative effects arising from unjustified expectations. Be grateful for everything you have, even if you don't have much.
6. Forgive yourself for mistakes
Chances are you did a lot of stupid things in your 20s and teenage years. Everyone is wrong. But now you're 30, and it's time to reflect and forgive yourself for all these mistakes. People who engage in introspection see their weaknesses and try to avoid similar mistakes in the future.
Learn from your mistakes, forgive them and move on. Don't dwell on the mistakes of the past.
Psychologists say that the ability to forgive yourself and learn from your mistakes is a key factor in achieving success in anything.
7. Start exercising regularly
Find time to exercise. Thank you in the future. Loss starts after 35 muscle mass, and due to a slowdown in metabolism, a few extra pounds will appear. That's why it's especially important to start exercising early.
As much as possible. It doesn’t matter what exactly you do: hiking, jogging, hiking, swimming or weightlifting. The main thing is to practice. Choose the right kind physical activity that you really like: less likely to give up halfway through.
8. Call your parents more often
Most 30-year-olds spend all their time doing family affairs, their own careers, and in this cycle they forget to maintain relationships with their parents.
Remember that your parents also get older and that they don't last forever. If you do not show enough care for them, then such an opportunity may not be, and you will repent.
Call your parents regularly. Just to find out how things are and let them know that you're okay. This will support their mental and emotional well-being, making your relationship warmer and stronger. Visit them at every opportunity.
9. Proper nutrition comes first
Another thing to add to this list is to get into the habit of eating right. If you do not start eating at 30, then in 40 and later, health problems will appear that could have been avoided.
Eat a balanced diet, reduce your intake of carbohydrates and fats, add more vegetables and fruits to your diet. Avoid convenience foods and fast food. Quit smoking and excessive alcohol consumption. And, of course, no drugs. Health should be in the first place, because this is your main wealth.
10. Keep enjoying life
Don't stop having fun just because you're over 20. If you spend your 30s chasing money, you'll end up as a surly, cynical, unhappy person.
All people who have left their 30th birthday far behind unanimously declare: no money is worth it if you do not enjoy life.
So enjoy life and have fun while you can. Go on dates, play with your kids (if you have any), friends and see the world. You only live once. So why not live this life the way you want? Enjoy this age, accumulate wonderful memories and do not forget about your goals.
A couple of years ago, you could eat whatever your heart desires at any time of the day and this did not affect the figure. You could not sleep for half the night, and wake up cheerful and rested in the morning. However, after 30 years, the situation is steadily changing. What to pay attention to stay beautiful and healthy?
1. Sleepless nights
Sleep is an important part of our life. During a night's rest, body temperature drops, heart rate drops, and brain activity changes. And all this in order for the body to be able to recover.
It should be remembered that sleepless nights increase the risk of developing heart disease. Sleep deprivation irreversibly damages brain cells. However, the very first effects can be easily felt after one night. Morning fatigue, poor concentration during the day, nausea, dizziness. The fact that you have not slept is also indicated by your face. Blood circulation worsens, the skin becomes gray, bags appear under the eyes. And the older we are, the more acutely it is felt. To recover, the body after 30 years needs at least three full-fledged dreams.
2. Lack of physical activity
After thirty, the metabolism slows down. The production of progesterone, a hormone responsible, in particular, for metabolism, decreases.
Imagine that your body is a machine, eh. It is enough to adjust three aspects of life to adjust the engine speed. These are food, exercise and sleep.
In addition to metabolism, there is another reason why exercise is important after 30 years. As the years begin to fade muscle fibers. This means that the muscles become less flexible and stronger. But muscles help burn calories. The weaker they are, the slower the body copes with metabolism. Without regular physical activity after thirty it is difficult to stay slim.
3. Bad diet
Remember the two golden rules. First - have breakfast, second - during the day, eat often, but in small portions, every three to four hours. If you skip breakfast and go to work on an empty stomach, you are confusing your brain. From the stomach comes information about the lack of "fuel" and the body begins to store fat.
Remember to avoid simple carbohydrates and sugars. There comes a time when even a minimal excess of calories instantly turns into fat.
A bad diet affects more than just being overweight. Due to the lack of essential nutrients hair can fall out and skin can deteriorate. To prevent this, eat vegetables and fruits daily, and fish twice a week.
4. You don't use creams
After 30 years, the production of elastin and collagen decreases, so the skin loses its elasticity. It becomes thinner and less elastic, so in some places cellulite is more visible. Do not forget about the appearance of the first mimic wrinkles.
The bare minimum is a good eye cream, a day and night face cream, and a firming body cream. Of course, they should be used regularly.
What cosmetics to choose? With vitamin C and E, with retinol and coenzyme Q10. Vitamin C brightens the skin and gives it shine, E protects against free radicals, retinol, i.e. one of the forms of vitamin A, stimulates cells to regenerate, improves elasticity and reduces wrinkles. Coenzyme Q10 affects the smoothness and elasticity of the skin. Moisturize your skin from within. Drink more water. Avoid too a large number coffee and alcohol. 
5. Alcohol abuse
If there is a lot of alcohol in your life, know that it damages the liver and pancreas, leaches minerals and vitamins from the body. The older we are, the more difficult it is for the body to cope with the metabolism of alcohol.
We think that at any time we can turn to parents, if suddenly something happens. And it's time to think that they can turn to us at any moment, and their problems will have to be somehow solved. You. As they say, the point is not that we are adults, the point is that adults are now us. It’s better to get used to it now, because your parents are not getting healthier and younger, alas.
Willpower will help you
One day you will gather with this very willpower and - wow, everything will work out! You will stop staying up until two in the morning, because it is interesting to watch another series, you will stop having coffee for breakfast, you will definitely learn Spanish and lose five kilograms. No, it doesn't work. Because the only thing you have to do is start, and then it will either become a habit or you will enjoy it. Or you will abandon the idea itself in principle. Well, or you will still wait for the grace that will descend on you. So-so idea, to be honest.
You fit into the jeans you wore in 10th grade
No, you won't get in. If you set yourself the goal of stuffing your aphedron into teenage panties, write wasted. Because youth is over, and you understand that. And even if your body type allows you to return to the same size, you will not succeed. Precisely because you still haven't thrown those jeans away. Your consciousness intends to return not the volume of the hips, but the wonderful young years. Which, of course, is impossible. Throw away that relic rag and buy yourself a gym membership.
Problems will solve themselves
Yes, yes, “Never ask for anything! They themselves will offer and give everything themselves. Do you remember where the quote is from? That's it. They will come and give - without fail. On the neck. In the event that you do not analyze situations of this kind that have already happened to you. And you won’t understand that your problems have never been solved by themselves: either they were solved by people who love you, or you figured it out yourself, just didn’t think about it, because, in essence, nothing terrible happened. And now you have grown up, the problems have become adults. It's okay, really - if you don't wait for it to somehow resolve itself.

Loans are convenient
An amazing thing: more than half of Russians aged 25 to 64 have a higher education, and no one still knows how to count, judging by how often we take loans. And if at the age of 20 the thoughtless waste of money is still forgivable, then at 30 it is somehow strange. Let's leave the question of survival - a loan for treatment or a mortgage loan. Let's take sudden expenses - the refrigerator, for example, is broken. No money for a new one. Don't have savings because you can't afford it? Can you afford to pay at least double? I wonder how it turns out?
Can you lose weight for summer?
In general, yes, you can - if you start losing weight in September. No other options are provided. Yes, 10 years ago you could go on an express diet and lose weight in just a couple of weeks, but now this joy is over. But now you can undermine your already imperfect health, get a couple of extra wrinkles and sagging skin, and then gain back everything that you lost, plus a few more kilograms. Great prospects, right?
There's still time to fulfill the dream
No. Not because active life ends at 30 and it's time to wrap yourself in a sheet and head for the necropolis. You do not have this time, because you are still dreaming, but you should already be making plans. The difference is very significant.
If you're good, nothing bad will happen
There is no heavenly office that distributes to everyone according to merit, in fairness, and to some in one place with a shovel. You can't keep yourself out of trouble by following some code of "goodness." You can and should buckle up in the car, visit the doctor prophylactically, and not when something is already falling off, and do not forget to analyze what is happening in your personal life. Being a good girl is also possible, but not necessary. I mean, it won't save you from anything.
Tomorrow will be better than yesterday
Tomorrow will be much, much worse if you still believe in this mantra. It is very difficult to learn to live in the present if you are used to dreaming about the future, but it is simply necessary to do it. Not because a wonderful future will not come - it is quite likely that in 40 years everything will be fine with you. But you will not be able to enjoy it, because you will continue to dream about the future. And there, in this very future, menopause and retirement, in fact. Not that it's horror-horror, but, you know, it's a shame not to have time to enjoy everything that life gives you while you are young and full of energy.
Someone knows the truth
And now he will teach you, yes, yes. A guru will come and tell you how to live, and you will be happy. You will eat only raw vegetables and get healthier, you will run in winter and summer in a skirt to the floor - and your husband will earn a million, you will breastfeed your child up to 8 years and teach at home - and he will grow up to be a genius. Do you know what will really happen? You will undermine your health, waste time and money, and - most importantly - lose your self-respect. Because there is no happiness for everyone and for free. There is no magic recipe for a happy life. You will not achieve anything, but you will lose a lot if you do not understand one simple thing: no one knows the truth, because it simply does not exist. Not provided in the basic configuration of the universe.
He's just having a tough time.
No, he's just a mouflon. And you understand that very well, by the way. 30 years is the time when you need to understand something else: you are already a big girl. You don't need a walker to walk through life. You can be alone, you can be in a couple, and the only thing you can't do is be with just anyone. Because right now is the heyday: you are finally an adult, but still young and beautiful. This best age women. It is very foolish to spend this magical time taming ruminant artiodactyls.
We are all used to the fact that bears are dangerous ferocious animals. To face such a predator in the wild is to face death (everyone mentally imagined the Oscar-winning "Survivor" and nodded).
Fifi is a Syrian brown bear. There is absolutely no anger in the eyes of this poor animal. But there is pain, incredible fatigue and a completely sincere misunderstanding of why she had such a cruel fate.
Fifi spent the first 10 years of her life in a cramped cage at a roadside zoo in Pennsylvania. When the zoo was closed, the owners of the animals did not give a damn about the bear and her three relatives, leaving the predators to languish in cramped cages that were not adapted for keeping bears. Fifi lived in this prison for 20 years.
Although its existence can hardly be called life. The animal was not walked, it was poorly fed, it had no access to water. The worst thing is that the bear was not allowed to hibernate, which means that her body was at the last stage of exhaustion.
Last summer, owner Fifi decided to get rid of the bears. PETA workers arrived to pick up the animals, who were shocked by the state of the bear: thin, the skin hangs down, in places tight to the skeleton, her eyes are sunken. Fifi was later diagnosed with arthritis in her hind legs. She and the other bears periodically swayed back and forth, a movement the animals use to cope with stress.
The bears were transported to a wildlife park in Colorado as soon as possible, provided with proper care and proper nutrition. For the first time their paws touched the grass, the water in the pool, the first time they tasted the fruit.
Freedom and careful medical supervision transformed Fifi in an amazing way. The she-bear gained weight and acquired thick, long, coffee-colored fur. Thanks to the people at PETA, Fifi will be fine now.
We lose hair every day, but we usually don't go bald; we cut our nails, but they still grow back. We remove dead skin cells to give it smoothness and radiance, we carry out procedures that start the process of skin regeneration.
All this is possible thanks to the body's ability to renew itself. You must have heard that the human body is completely renewed every 7 years, that is, at the end of this period you become a different person, because every cell of your body is replaced by a new one.
Sounds amazing! But is this really so and why do we, despite the renewal of the body, continue to age?
Body renewal: each cell has its own “service life”
Indeed, the lifetime of individual cells human body limited. After the expiration of this period, the cells die, and new ones take their place. The adult human body consists of a huge number of cells - approximately 50-75 trillion - and each type of cell has its own "lifetime".
After the death of a person, not all cells die immediately - some of them take several minutes for this, others - hours, and others - a day. The rate of cell death is one of the factors that is used to determine the cause and time of a person's death.
The rate of cell death is one of the factors that is used to determine the cause and time of a person's death.
Below site will consider:
- the approximate time of renewal of various cells, tissues and organs of the body;
- why do we get old.
How fast is cell renewal?
Below are the approximate rates of cell renewal in the human body:
1. Red blood cells (erythrocytes), which carry oxygen, live for about four months.
2. The average lifespan of white blood cells is just over a year. At the same time, the most numerous group of leukocytes - neutrophils - live only a couple of hours, eosinophils - 2-5 days.
3. Platelets live for about 10 days.
4. Lymphocytes are updated at a rate of 10,000 cells per second.
5. Epidermal cells are updated approximately every 10-30 days of the week, the skin recovers 4 times faster after minor injuries.
6. The "age" of hair on the head can reach 6 - 7 years. Every day, the hair on the head grows by about 0.5 mm. Hair on other parts of the body - about 0.27 mm per day. Eyebrows are renewed every 64 days.
7. The surface of the cornea of the eye is covered with a thin layer of cells that are constantly updated in 7-10 days. Retinal cells do not renew themselves, as does the lens of the eye, so age-related visual impairment is a common problem. However, experts are developing methods of retinal regeneration using stem cells.
8. The epithelial cells of the small intestine are renewed every 2-4 days, the colon - about every 4 days, the gastric mucosa - about 5 days.
9. Cells in the cerebral cortex, as far as we know today, are not capable of regeneration, unlike hippocampal neurons. Damaged nerve cells can recover to a certain extent if the body of the neuron is not damaged.
10. The rate of nerve regeneration after injury is approximately 2-3 mm per day.
11. The average age of a fat cell is 8 years. Every year, 10% of fat cells are replaced by new ones.
12. Renewal of liver cells takes approximately 300-500 days. The human liver has an excellent ability to regenerate. If you remove 70% of this organ, it will recover to normal size in just a couple of months. Surgeons removed even 90% of the liver, but recovery in this case was incomplete.
13. Kidney and spleen cells need 300-500 days to renew.
14. Nails grow about 3.5 mm monthly, although the pinky nail grows slower than the others. Toenails grow at a rate of about 1.6 mm per month, with the thumbnail growing the fastest.
15. The heart is one of the slowest regenerating organs. human body. In a 25-year-old person, only 1 percent of heart cells are renewed annually, this figure decreases with age. Less than half of the heart cells are renewed in a lifetime.
The heart is one of the slowest regenerating organs in the human body.
16. Taste buds on the tongue are updated every 10 days.
17. Fingertips can partially regenerate after injuries. The best results are observed in children a few months after the injury. An unaffected nail bed is needed to restore the fingertips. The new fingertip is sensitive and has an imprint.
18. The mucous membrane of the bronchioles is renewed every 2-10 days.
19. Microscopic air sacs - alveoli - are updated in 11-12 months, and superficial lung cells - in 2-3 weeks.
20. Muscle cells are "long-livers" because their lifespan is 15 years.
21. The cells of the skeleton are constantly updated, but rather slowly - 10% per year, and it takes about 10 years to completely replace the cells of the skeleton.
Why, despite the renewal of the body, we age
The fact of renewal of the body was established in the early 50s in the course of observing the movements of objects with radioactive atoms embedded in them. Jonas Friesen, a molecular biologist from Sweden, has been studying body renewal by measuring levels of radioactive carbon-14.
He found that every 7-10 years most of the body's cells are replaced by new ones. Of course, this figure is conditional, taking into account the rate of renewal, for example, of heart and skeletal cells or the lack of the ability to regenerate certain neurons, retinal cells, lens, and oocytes.
However, with age, the body's ability to regenerate decreases, and effective method prevention of aging and death has not yet been found.
Geneticists believe that the cause of aging is hidden in cellular DNA, or rather, in its terminal sections - telomeres. There are several theories of aging, as well as a number of factors that influence this process.
Scientists continue to study the features of body renewal, the causes of aging and methods to prevent this process. the site hopes that one day they will be able to give the world a revolutionary discovery, thanks to which the immortality of man will become a reality.
