My feeling is that longevity will have an s-curve effect. Every disease and malady we solve today only extends life until some other problem kills you. However, the further we push things, the more problems we are capable of resolving, the fewer things that will pop up and kill you - until, probably surprisingly, people are living significantly longer lifespans than ever before.

The most generalised effects of aging will probably be the most problematic (muscle loss and the like), but there are plenty of stories of people in their 90s who are plenty spry until they are brought low by a heart attack, stroke, cancer and so on.
