Title. Why do our bodies stop growing at one point and begin to decline in function? If the purpose of life is to live and reproduce, wouldn’t it make more sense to continually evolve and live forever? Also don’t our cells constantly regenerate? So if they do then why do they start to die out?
In: Biology
Because entropy is terrible.
There’s only a few ways for things to be put together and work, and many, MANY more ways for things to be put together and *not* work. And the longer something exists, the more and more *slightly* off the way it’s put together will be until it finally reaches one of the infinitely many “doesn’t work anymore” states. Whether it’s external damage building up atom by atom, the cell division process going slightly wrong gene by gene, etc. Anything that can do stuff will cease to be able to do stuff before very long, that’s the nature of everything in this damn universe, *especially* life.
