Note that a bunch of posts on this topic have previously been written - so probably worth checking them out first: See: https://forum.effectivealtruism.org/topics/aging-research

Many of these were from 3-5 years ago, so it could be worth providing an update. It could also be worth creating a really thorough overview of the various arguments in one post, assuming none of the previous posts are in-depth enough, or lots of points are spread out across numerous posts. 

OpenPhil likely has some research on this — they fund work in this area https://www.openphilanthropy.org/grants/university-of-california-berkeley-aging-research-irina-conboy-2023/

I'm neither an expert on aging, nor a biologist (only a silent consumer of the aging literature and stuff that Prof. David Sinclair says about the topic). Just wanted to say that I'd love to read a post on this!
