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:

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).
A very interesting thought to me is that in order to live (almost) forever, your natural life span doesn't need to reach until the holey grail of longevity is found. You just have to live long enough until they come up with something that extends your life let's say 25 years. And within these 25 years they may find something that gives you another 30 ...and so on.
That means there might already be people on the planet today that will live (almost) indefinitely...
