OT: If someone is interested in personal longevity "enhancement":

Nothing there yet, but there are two majors (Altos labs and Calico) and several more specialized companies worth noting:

Altos raised 3bil just to start, so it is, potentially, a future "monster", but they are still at the research phase.

Imho, the best shot at longevity treatment right now is, paradoxically or not, some anti-diabetics/weight loss medications: ozempic/wegovy (and similar, like mounjaro) and metformin. Among the companies above, there are some that could give you better diagnostics, but their benefits are less clear.

This is pertinent unless you don't care about personal longevity and work mostly on transferring your sats to the future generation(s).
