I wasn’t trying to describe the root causes of aging. I was trying to distinguish between diseases that are avoidable via lifestyle changes, and age-related diseases that are sufficiently determined by our genes that we’ll need major new technology to avoid them. The latter include things that impair our immune system and repair mechanisms.
My best guess is that the root causes of aging involve some clock-like processes that have been actively selected for different metabolism at different ages. See Josh Mitteldorf’s writings if you want more on that topic.
