What processes cause aging?
The topic for this week, "What processes cause aging?" is very related to last week's question of "Why we age". Essentially, they are two separate questions, but often go hand in hand. While we didn't discuss every theory related to aging (there are hundreds!) the chapter presented some examples in addition to what your classmates also discussed or linked to in their own blogs.
For this week, I have two tasks:
1. Read the blogs of your classmates. Either leave a comment or pose a question regarding something they linked to or discussed (this can be previous posts).
2. Create a short post mentioning something interesting you read about for this weeks readings.

I found it interesting how the author related aging to a car rusting. So with oxidization it's like we're all rusting on the inside.
I also found it interesting that they discovered mice with low calorie intake seem to age more slowly. Would this make perpetual dieting or leading a low intake type of lifestyle result in a slower aging process for humans? And I suppose a better question would be: how is aging measured . . .
Totally unrelated, but once upon a time a lady who looked 25 but was really 45 told me that she was once a professional ice skater and believed that the cold of being in the rink practicing all the time had "preserved" her and frozen her youth. And off the top of my head, I can't think of any haggly looking ice skaters.
I also was impressed with the author's comparison between us and a car that is slowly rusting, I thought that was a very interesting comparison, good job!
ReplyDeleteI like your questions delving deeper into the reading. A lower calorie intake certainly does seem to make most creatures live longer, based on the evidence brought up in the reading.
ReplyDeleteBased off the ice-skater's anecdote, one would think that living in the far east of Russia or the Artic Circle would dramatically increase your life span, which off the top of my head doesn't seem to be the case.
Sara,
ReplyDeleteInteresting anecdote. Some scientists have actually tried to put themselves in a "cooler" to delay the aging process.
Riley- You make a great point as well. As for the ice-skaters, it could be their exercise/diet also has an impact on their health-ful appearance.
