Unbelievable facts
Even if you don't have a single illness or injury, you'll still die of old age.
Why didn't evolution stop aging? Scientists have come to the conclusion that this is simply mathematically impossible.
One explanation why evolution has not eliminated aging is that aging is only a problem after we no longer produce offspring.

As soon as you can't give birth to any more children, evolution is done with you.
However, evolutionary biologists at the University of Arizona say that everything goes much deeper. Aging is a fee for admission to the club of multicellular organisms.
The immortality of life
The problem is related to two things that occur with aging cells: their growth either slows down or accelerates.
You may notice how cell growth slows down when you get gray hair and hair cells stop producing pigment, or when wrinkles appear because your skin no longer produces collagen and elastin. We're all used to this kind of aging.
When cell growth accelerates, this is a cause for concern, because it can lead to the formation of cancer cells.

But as scary as cancer may seem, it's just as much a part of aging as gray hair and wrinkles.
It is when symptoms appear that it becomes a problem. For example, half of men over 60 have prostate cancer, but it usually doesn't develop into something dangerous, and many die for a completely different reason.
Human immortality
The researchers simulated the evolution of traits that cause cells to slow down or accelerate, and what they found provides the definitive answer.
If they find a way that doesn't slow down cells (no wrinkles or gray hair), you'll be killed by fast-growing cancer cells. If a way is found to stop cells from accelerating, slow, poorly functioning cells will start piling up and kill you.
According to scientists, aging is mathematically inevitable. This is logically and theoretically impossible.
The fact that we are multicellular organisms means that cells compete with each other. Try to break this balance, and the situation will only get worse.
We can prolong life, but we can't stop dying. That's why it's so important to value every moment of your life.
