Of course, that's what "raise" means. Grandmothers also raise their grandchildren -- google "grandmother effect" or "grandmother hypothesis". I'm more talking about people who want to raise life expectancy from 100 to 200, not go from 70 to 100 (not sure where the original article fell on this). 70 to 100 is clearly possible and we've already gotten a long way there in the 20th century (antibiotics, etc.) The "problem" now seems to be that not everyone actually cares if they live that long... i.e. there are plenty of people who don't want to live to 100, and might not even if they maintained the health of a 60 or 70 year old.
