Why do we get old.
Maybe evolution is dependent upon aging. If evolution can be dependent. I guess this is anthropomorphism... but so is evolution... come to think of it... least from my POV... being somewhat anthropocentric.
If there is boundless energy and space, why can't there be boundless existence? If there isn't boundless energy and space... why isn't there?
I can see growing... I mean... how else could we get out of each other? But cellular rejuvenation is only necessary because they age... correct?... or are damaged beyond functionality. I suppose cellular aging means that they need replacing which means that by replication there is the possibility of mutation which is essential in staving off disease...[and the cause of disease both endogenous and exogenous] but again I am assigning forethought to evolution. Mutation being tantamount to evolution and all.
Why can't I decide to switch it off? Say I'll take my chances on some exotic disease ravaging my cells against cancer and the inevitable conclusion when aging culminates. Then again, even cancer needs aging in a roundabout way... it needs the cell replication process which prime motivator seems to be replacing old cells.
So what causes cells to be worn out?... slipped electrons?...displaced atoms? I guess they have to incur physical damage of some sort... but why? Why should they be so fragile? To what end? It is all to do with the reality that we inhabit... and that isn't a satisfactory answer... but it will have to suffice I guess.
Mind boggling! I agree.
If God was responsible for us, God has some serious explaining to do, because He made some pretty horrible mistakes.
Anyway, dawnathen's horribly simplistic answer doesn't really cover it, does it? Let's go deeper.
There are many theories about why we age. One is that the cells in our bodies have a built-in genetic trigger that shuts off their regeneration after a certain period of fertility. The idea is that after we've spread our genes, why should we stick around?
Another theory suggests that over time, particles called free radicals build up in our bodies through pollution, disease, diet, and other factors. These free radicals interact with our cells in a negative way, causing them to break down and eventually die.
One interesting study suggests that we age according to how many calories we consume, and that going on a restricted-calorie diet can increase lifespans by as much as 50%. You'll be hungry all the time, but you'll also live to 150. Hm.
everything living has to die
people die, animals die, plants die,ect
things die so evolution can take place
so things can evolve to adapt to there surrounding enviroment
if things lived forever there would be no room left on any planet after a while
everything would be over-populated with life, and just keep reproducing
things need to die
well, because our body organs fade over time like color if you hold a red paper in the sun, over time it will fade, our organs that make us livve eventually stop workingg.
I read the answers I agree with other members of fun advice.who ever born has to die one day even earth,sun & universe itself getting older is the last stage of the life
wow because of the way our dna is structured and our genomes and god wants us 2 b old I guess?
due to the accumulating effect on body cells. As we stay longer on earth, we get old
It wouldn't be fun to stay young forever. It's just the way God made us.
because living forever would suck
I dont no
