Eli5 how does natural death work? Why do we age at all?
In: 5
This is _very_ simplified, but basically our body is constantly repairing itself using DNA as the instruction set, but out DNA deteriorates with time. Every time a cell replicates, DNA has a chance of getting corrupted, and there’s evidence to suggest that cells can only reproduce a certain number of times regardless.
And when DNA gets corrupted, there’s a chance it turns into cancer. Which, frankly speaking, is what most “natural causes” death ends up being.
