Apr 29 at 20:41 comment added John A cell that can divide indeifnetly without end in a body is either a stemm cell or a cancer cell. you want cells to have limited replication in a multicellular organism to prevent the latter.

Apr 29 at 4:08 comment added Jiminy Cricket. Perhaps your researches need to include some basic evolutionary ideas. The reproductive years are over by the time senescence sets in. The flip-side argument would be: Why would we have evolved to live longer than we do?

Apr 26 at 23:19 comment added Rookynote Thanks for the article! I've tried to do some research, and only really found things about cell division and mutations. I suppose it is hard to research when you don't exactly know what you are searching for haha! Now knowing about Senescence, I'm still left with the same question of why it happens (this just seems to imply we know it happens). I'll be updating the original question accordingly. Thank you!
Apr 26 at 8:27 comment added Domen Welcome to Biology StackExchange! Generally, it is expected that you do some prior research on the question yourself before posting it here. Ageing and senescence are very complex topics, and there are many different theories trying to explain these phenomena. You can start with a Wiki article on Senescence and familiarize yourself with the basic terms and concepts :)
