I have many posts that I want written but do not have time to write and I suspect there are other people that feel similarly. This post on the Solomonoff prior was one example, until I got fed up and just wrote it.
Please write one post idea per answer so they can be voted on seperately.
Much of the harm of aging is the increased likelihood of getting many diseases such as cancer, heart disease, alzheimer's, and strokes as you age. From my limited understanding, Metformin reduces the age-adjusted chance of getting many of these diseases and thus it's reasonable, I believe, to say that Metformin has anti-aging effects.
