why our body is able to self heal but it will stop working and let us die when we get old?
In: 3
Some of it is wear and tear (scars, mutations, etc) but a lot of it is evolved. There’s structures on our chromosomes called telomeres that protects the data, but they shorten each time the cell reproduces which effectively tracks age. The shorter the telomeres, the more likely mutations occur which both results less efficient cells and cancers.
There’s a lot of hypothetical reasons why it’s beneficial not to be immortal but dying of old age seems pretty much hard programmed to happen as you get near 80 (some variance based on healthy lifestyle and genetics of course)
