Ask HN: What can I do today to prepare for anti-aging tech of the future?

Given the state of anti-aging research today, is it clear yet which technologies will be the first to have some success at prolonging life? If we have a general idea of what classes of technology will be available in 20-30 years, then we should be able to guess what it will not be able to do, or what constraints it might have that increase its effectiveness.

What anti-aging technologies will be available in 20-30 years, and what can I do today to prepare to derive maximum benefit from them when they arrive?

I’m looking for answers beyond the obvious exercise and be healthy, although I should probably start with that. :)
