Hi everyone
I take my hat off to jwfacts for recommending an excellent site, namely www.ted.com. This website is full of visionaries and people with wonderful ideas about the future. The website is kind of a "youtube" of academics, where scientists and entrepeneurs pitch their visions of the future in brief talks. Needless to say, the "talks" shown on this website are infinitely more edifying than the talks we grew accustomed to at our kingdom halls.
The theme of one talk grabbed my attention - "Experiments that hint at longer lives" by Cynthia Kenyon.
http://www.ted.com/talks/cynthia_kenyon_experiments_that_hint_of_longer_lives.html
I'm increasingly interested in this field of human science since acknowledging my own mortality when I mentally left the Borg. On the one hand, I relish the challenge of doing as much meaningful stuff in my 40 to 60 remaining years as possible. On the other hand, I am slightly nervous that this is all I have, and I wouldn't mind having a bit more, if at all possible.
Kenyon notes that there is a huge variance of lifespans within the animal kingdom. It is almost as though there is an invisible dial that is tuned to different ages, depending on the creature. For example, the lifespan of a mouse is 2 years, whereas the lifespan of a bat is 50 years. The difference? The genes of one species allow for reduced aging in comparison with the other.
Kenyon then describes experiments with a type of worm that normally dies within a month. Individual worms within a control group with just one simple genetic mutation were able to live TWICE as long as their 'normal' counterparts.
I find this sort of thing extraordinary, and the possibilities seem endless. What if one day we can have our genes altered, thereby slowing down aging, or halting it entirely? I'm not getting my hopes up too much over this, but it does seem that the potential of science to impact on human longevity may be more significant than we realise.
Thoughts anyone?
