Ask HN: How to make sure I'm able to use future life extension tech?

Hypothetical example: It's 2030, a new anti aging tech adds 30 years to lifespan, but it only works in people with really healthy livers. Based on what we know today about likely anti aging tech, are there certain things we should do or avoid doing today to be able to take Max advantage of any breakthroughs that are hopefully soon to arrive?
