Disclaimer: I'm trying to (sort of), and I know there are a lot of initiatives. I'm just curious to why there isn't more, given what's at stake.
So, because a successful long-term research project needs good human capital more than almost anything else, it helps to have:
1) Good rewards for small successes. This could be easy for life extension research if the intermediate step of "add 1 year" is rewarded well and the reward is public (so people know the reward is there).
2) An allied industry which provides jobs for "failures", from which they can regather strength before jumping back in. Silicon Valley has done well because failed software startup founders can work at a big software company for a while before jumping back in. Fusion suffers from the fact that once you get a job in another industry, jumping back in is difficult. I don't know if medicine is so specialized that this is a problem for aging cures.
3) A popular perception that the goal is achievable. Fusion does better at this than curing aging. This ties back into the "reward small goals" in point 1; publicly achieve small goals and the big goal doesn't look so impossible.
Good luck! We all hope you are able to contribute to an aging cure!
Certainly we know by now Earth's resources aren't infinite ... So I pose to you what could come from Pandora's box should choose to open it.
Wisdom an Experience come from aging, where do we go, and how do we grow, if that aspect of life becomes irrelevant?!
We shouldn't try to create an electric self-driving car because it might kill somebody, but people are being killed by non-self-driving cars, so are we really any worse off?
If the limit of Earth's resources means that we will run out and some of us who would live longer will die earlier than we'd hope...well, we're already doing that.
