From a biological/scientific perspective, why do humans die?

Free redicals cause cell damage, resulting in eventually cells not being able to continue.

Thanks for the simple explanation!

I haven't taken a science course since 2014 (my senior year of high school), so my memory is rather rusty.

Your telomeres quit working.

Cellular boredom. Keep you cells entertained. At least that's what Dr. Geiger says.

Yes, I remember learning about telomeres in biology. They get shorter and shorter as we get older.

So how can we live longer? What do you mean by entertainment?

It was a joke from an episode of Star Trek.

Oh! I've never seen the original star trek. Excuse my ignorance. lol

OK, now a serious answer...

The various tissues and organs require resources to maintain in usable condition. The longer they exist, the more repairs they require. At some point it offers no evolutionary advantage to extend the life of a individual after reproduction has completed.

Oh! I find the scientific answers interesting and I love learning more and more.

Thanks for the response!

As I recall, it's been estimated that about 120 billion Homo sapiens have ever lived on the earth. Death is an ecological necessity. If none of our species--or any living animal--didn't die, our planet would be depleted of resources. Not to mention that the fossil record suggests that all multicellular animal species eventually go extinct. (Plants seem to be more resistant.) So unless we develop the technology to leave Earth and colonize other planets, the same fate will befall us.

The common possum lives about three years,
a turtle for maybe a hundred.

#1: Humans are animals and animals generally die.

#2: Thermodynamics is a harsh mistress. Our bodies can only hold off entropy for so long by eating other living things.

"Cellular aging is due to intrinsic factors. It’s related to the biological aging of cells. Cells are the basic building blocks of the body. Your cells are programmed to divide, multiply, and perform basic biological functions. But the more cells divide, the older they get. In turn, cells eventually lose their ability to function properly. Cellular damage also increases as cells get older. This makes the cell less healthy, causing biological processes to fail. Cellular damage accumulates over time, too." Healthline

Here's some interesting news I read about recently - Two Research Teams Reverse Signs of Aging in Mice

I find this all fascinating. I hope that doesn't sound morbid.

Most early death can be avoided through diet. Dr Ornish has proved this again and again.

Diet and exercise. You insurance will pay for you to go through programs to teach you how to live longer and how to be more healthy. They are paying right now for a physical therapist which cost a lot more than I can afford to pay.

Good question.

John 11:25 Jesus said unto her, I am the resurrection, and the life: he that believeth in me, though he were dead, yet shall he live:

1 Corinthians 15:6 After that, he was seen of above five hundred brethren at once; of whom the greater part remain unto this present, but some are fallen asleep.
