Anti-aging focuses specifically on extending the “healthspan” of people (starting in the developed world, presumably) past the current point where age-related degenerative diseases start to eat into your QALYs.
It’s different from disease prevention because it operates higher than at the level of individual diseases, hoping to solve the underlying reasons why age is so strongly contributory to those diseases.
Anti-aging also tends to have absurdly high RFMF compared to most disease research, since it’s a “weird” idea that most people don’t like.
It also seems high impact: it would serve as a multiplier for any earlier-in-life health improvements as well as allowing some high-skill people to keep contributing to society (e.g., researchers who have accumulated lots of valuable knowledge and experience).
Practice thinking about EA related stuff in your daily life.
Even if you don’t always take the action, even just thinking about it can start to build the mental patterns which you will be able to follow later.
What food would I order today if I were vegan?
What job would I take today if I were earning to give?
How would a utilitarian analyze this ethical dilemma?
