Title. Why do our bodies stop growing at one point and begin to decline in function? If the purpose of life is to live and reproduce, wouldn’t it make more sense to continually evolve and live forever? Also don’t our cells constantly regenerate? So if they do then why do they start to die out?
In: Biology
1. cells take on damage over time (UV, toxins, metabolic byproducts)
2. replication errors in DNA
3. telomere shortening (every time a cell divides the telomeres that help it divide get shorter)
