Rejuvenation Pills

No one likes getting old. Everyone would like to be immorbid. Let's be careful here. Immortal doesnt include youth or return to youth. Immorbid means you stay hale and hearty.

I've convinced that we humans have pupal, larval, and adult insect stages, seeing as we are ape-shaped bugs, really. Funny little bugs, floating on a ball of lava, at the bottom of a razor thin ocean of air. There's no molting or cocoons, no overt dramatic stages,  but there are stages. Puberty obviously, but research have shown body changes at age 40 and 60. One more late stage adult change, I suspect, happens around 80, where you turn into a tough old bird, or a fragile and more gracile one (both are useful adaptations).

I'm laying the ground work for the rejuvenation pulls discussion. Recognizing biology, we eliminate pills that can turn you into babies, or with lack of access, turn you into a corpse in front of our eyes. Much as I like that stuff, it's unrealistic bullshit.

So, rejuvenation pills might take you back to a prior stage. If you are 60+, you go back to 40. If in you're in your 40s, welcome to 25. Anyone taking the pill before age 25 has no known effects. Let's not rule out compounding, so that someone aged 80+ could over time go back to 25. 

If you hated Boomers, just wait.

Rich people want this kind of immortality, and given the statistics on generational wealth being solid, it's a good bet. You risk the occasional chaos, but you assume if things take a shit you can't get the pills anyway. In which case you age normally, or if things have really taken a shit, die.

But let's say things take a minor shit, a bottleneck, and the rejuvenation pills either have a lasting effect, or are available, many of these bunker billionaires find themselves slaves to the Furious Host. The Great Unwashed Undead Survivors. Immortal Barbarism? Nah. Like it or not we are a superorganism. But the irony of Elon Mush or Donnie some war lord's butt, is funny
