I get this feeling that we've already discovered the highs (or we're close) of the population average. Individuals may get older more than they used to, but as a group there's also a lot of people exposing themselves to risks that didn't exist in our hunter-gatherer past. Too much food and too little exercise kills a lot of people. Of course not everyone will eat themselves to death, and there have been advances in both other areas of medicine as well as public information. But it seems like the top causes of death are basically linked to eating wrong and not using the body the way it was meant, both of which are not so simple to fix, even if you solve the difficult problem of the telomeres and all that.
