The most important thing in the near future of life extension is Sirtris Pharmaceuticals's super-resveratrol, SRT501. Resveratrol is one of the beneficial substances in red wine. SRT501 lets you have the equivalent of 10,000 bottles worth of red wine with none of the poisonous effects of alcohol. SRT501 is much more economical than natural sources of resveratrol, which are currently too expensive to be useful for life extension, unless you want to spend around $100 a day. If I had money right now and they weren't denominated in the US Dollar, I would buy their stock.

The death of mitochondria hastens death from "old-age". SRT501 and resveratrol increase the number and function of your mitochondria. SRT501 is currently in clinical trials for diabetes and I fully expect it to increase average life spans by at least 10%, though this is not what it is getting FDA approval for. The day it hits the market I'm going to get an off-label prescription for it, as long as I can afford it.
