On Why Aging Happens.

I evidently got a little mixed up with the assignments, so this is a bit out of order but better late than never...

     Before getting into this reading, "Why Aging Happens," I want to sort of predict that it will delve into many biological aspects of aging which I am truly excited for and feel I will understand well.  Though I was thrilled coming into this class expecting it to  focus primarily on psychological aging, but I like that we are starting with the biological perspective on the subject.

     Well off the bat this reading makes more sense knowing that Senescence means aging/ growing old.  An early point made in the theories of aging involves scientists finding the subtle changes in our body  which correlate with aging. I use the word correlate for though the article calls them "signs" or "causes" of aging how do we prove this.  If the changes are so subtle how is it we categorize them with aging and not just living? It is strange to thing of ways to quantify the aging of a biological organism.
     I find the evolutionary theory "for the good for good of the species" theory. Saying that aging is not a personal benefit but is necessary for the success of others living.  We don't age for our own benefit but for the good of the population. For if individuals didn't age and die evolution could not happen. So we age, and we die, and we allow for our species to adapt to the world which naturally changes around us. Were just that kind I guess, we give up our youth so more youth can come in better adapted and live life for us...So we must die for we can not adapt as individuals enough to outlive the elements (this is assumed), and in order to die we must age right?... I suppose we could stay youth... its possible, but this could get into a sociological idea where populations must have a variety of ages and death must happen. But then the individuals would need to be more capable of various tasks and adapt individually (or maybe that is what aging is, just the reaching adaptations and the progressing after experiences): a topic I feel could carry on for quite some time.
p.s. this "for the good of the species" theory tells of aging as it applys directly to death, but without considering why death happens can we look at aging by it self..

     I find this theory to be quite interesting though, I look forward to discovering more theories and creating new opinions on the topic.

I did find this which talks about many theories (including our mitochondrial build up theory and more) but I was particularly interested in the Telomerase Theory of Aging which applies to the microscopic world and funnels down to the molecular biological level, saying that we die cause our cells die, because their DNA dies.  This applies to the telomeres and their shortening as they divide and create new cells. This brings me to question: what about the idea that death is part of a destiny? Like when we die is coded into our DNA?

I'm beginning to find I have more questions than I know what to do with.
