“The life expectancy at birth for men has increased by 20.5 years, from 58.8 years in 1920–1922 to 79.3 years in 2009–2011.”

Not sure what it would have been given you were 50 years old in 1920.

Anyway, you seem to not believe that science over the next 60-80 years will advance much.

People live to be over 100 today. Now it’s just a matter of figuring out why.

Science will advance more in the next 50 years than it did in the last 100.

I was talking about life expectancy for a 50 year old. Life expectancy at birth has increased significantly more because of reduced risk of death for newborns, infants and even teenagers. But once you are of a certain age, those risks are gone, and there not much has changed.

No, I don't believe in scifi. Theses are all fantasies. Just as little as I believe in living on mars being a great alternative to earth. Nice scifi story, but in real life, things are different.

If you just look at the spread obesity in the U.S. and its effect on life expectancy, please tell me again with a straight face that you expect "people live to be over 100" in the future. And no, they don't today. You are talking about a really really small minority, and that minority was already there 50 years ago. In 1970.

Edit: Life expectancy for a 50 yeah old in 1920 in Sweden was about 9 years shorter than today.

Why, yes people do live to be over 100 in certain groups:

I don’t think it’s unreasonable to think we’ll figure out how to extend this to more people.

Sure, if you don’t take care of yourself, science can only do so much.
