steve jobs was VERY sick due to being in extremely demanding business. Gates does not look healthy either. Most billionaires have gray hairs. Larry Page from Google is 50% gray at 39... Exception? Look at Qatar Emir or Prince Alwaleed. Slow business = more health!
I suspect that the first person to live to 200 has already been born. If you don't want to live forever, you don't have to...my suspicion is that people who say they don't would be first in line if the possibility became available. Otherwise, they and Hollywood want to appease the masses by convincing them that what they already have is best. Stockholm syndrome.
