I agree with you that UBI is the solution to 98% of labor condition issues, and that's a major reason I support it. But some fields pay primarily in some other currency (impact, social status, connections), so you'd also need UBsocialsupport, UBfeelingImattertotheworld, etc.
An incomplete and poorly vetted list:
People will probably bring up the claim that low calories extend lifespan. In the only primate study I'm aware of, low-cal diets indeed reduced deaths from old age, but increased deaths from disease and anesthesia.
I think some of the reduction just comes from being lighter, which is inconvenient but not a problem. But it does seem like people who lose and regain weight have a lower BMR than people who stayed at the same weight.
Weight science is awful, so grain of salt here, but: losing weight and gaining it back is thought to be more harmful than maintaining a constant weight, especially if either of those was fast. It's probably still good if you get to a new lower trajectory, even if that trajectory eventually takes you to your old weight, but usually when I hear about this it's dramatic gains over a fairly short period.
It's not just cars- helmets protect you if you tip over or crash into something. That happens at much higher speeds on bikes and scooters than while walking.
I wonder if dramatically shrinking the review's winners' circle would help? Right now it feels huge to me.
As someone who runs a lot of self-experiments and occasionally helps others, I'm disappointed in but sympathetic to this approach. People are complicated: the right thing to do probably is try a bunch of stuff and see what sticks. But people really, really want the answer to be simple, and will round down complicated answers until they are simple enough, then declare the original protocol a failure when their simplification doesn't work.
I think it would be valuable for George to write up the list of interventions they considered, and a case report on how he fine tuned the procedure for himself. Possibly valuable enough to pay for it. But I think he's doing the right thing by refusing to write out a formal protocol at this stage.
They are probably too long but at one point I ran this exercise with Master of Orion and Stardew Valley
