1. Removing senescent cells extends life by 30-40% with huge quality of life improvements in the last 25% of the life (relative to control), in mice. This isn't an elimination of all aging, but quite a valuable thing regardless. Eventually, other causes of aging would kick in and still cause death, without a single senescent cell in your body (e.g. DNA methylation). 2. I believe all governments should create Warpspee…

Maybe instead of maximising GDP we should maximise happiness and there's plenty of low hanging fruit. I mean people are still starving to death and dying of preventable diseases...

Do we want peak happiness, though?

Almost all advances of civilisation are created through unhappiness about something. Would a state of total happiness stop creativity?

We know who gets vaccines; it's in their medical record, if not centralized anywhere. Longitudinal studies aren't impossible. So any random hospital could do a longitudinal retrospective data-collection study on the consequences for their own patients of either having…

If you think its possible to pin point exactly what is the source of the problem with decade of various stressors piling up on anybody you should think again. It basically has infinite confounding variables. > those few poisoned bottles of aspirin did anything to increase the non-contingen…

Yes, but: Law of Large Numbers. The great thing about retrospective data-collection studies is that you can potentially get hundreds of thousands of histories as datapoints. With those numbers, basically every confounder washes away, other than the selection effect of "what kind of person frequents this hospital rather than some other hospital." And you can get rid of that confounder, too, if you meta-analyze studies done in hospitals in very different areas.
