I think answering the question of why we age is extremely complex, as demonstrated by the 300+ theories that are already in existence. The article "Why Does Aging Happen" presented two theories that I had not heard of before. The first theory regarding the good of the species was interesting in that some of the points made about the "survival of the fittest" and evolution seem applicable to aging and make sense when viewing only specific aspects of aging. While I can believe that evolution and the desire to adapt to a specific environment is important, if not vital, to the long term survivial of a species, I find it near impossible to believe that organisms age prematurely simply to benefit the rest of the population.
I believe the second theory about limited cell division is more accurate with regards to aging. While I do not have a background in biology or genetics, it makes sense to me that if our cells cease to divide and repair themselves, then our organs or body functions will also cease to operate as well, thus causing us to age. I still believe that there are other factors that effect aging however, such as nutrition, exercise, social stability and support, and mental activity. I am looking forward to discovering more about these variables as the class progresses.
I agree with your belief that there are other factors that go into aging besides biological/cellular processes. Your ideas of other factors are diverse and also very interesting to consider!
ReplyDeleteI appreciate the other aspects of aging that you mention-such as nutrition, exercise, social stability and support, and mental activity. As you say it is hard to believe that aging can be contributed to one aspect. Do you feel that these other aspects are independent from each other or do you think that they are all interconnected some how? Interesting points to consider, thanks for sharing your ideas!
ReplyDeleteI like how you included other aspects as to why we age but also having your basis be along science and cells, good job!
