We should fix health span first, not life span. I would rather live 80 like a champ to the last day and then just drop dead, then few more years on ibuprofen and friends.
They're heavily correlated, and nobody is talking about just increasing the length of life without also inherently making people healthier. People talking about working on longevity are talking about giving you more years where you feel 30 or 40, not just more years where you feel 90.
