If you die in your sleep, why is it that the heart for example just decides: Okay let’s just start not working.
Edit: I don’t mean heart attacks or strokes but more like “died in sleep, didn’t wake up next morning”
In: Biology
Because our cells are constantly dividing and replicating new versions of itself but every time a cell divides the DNA gets damaged a tiny miniscule amount but over the course of 80 years that DNA damage starts adding up. and It gets to the point where more bad cells are created then good ones.
Cells have a natural built-in system called apoptosis in which if they are not good they will kill themselves. If one or two cells do this no big deal but if most of them start doing this then problems are happening
