just to outline this fictitious would you rather, you rich enough to retire cryogenic preservation is perfect. you could live out the rest of your life in retirement and see the world evolve “like god intended”, or you can adopt cryogenic lifestyle where you freeze yourself for however long you want and stay thawed for however long you want but your still a human with natural human lifespan so you will eventually die.
of course contingencies are allowed if you think something cataclysmic will happened you can be dethawed abruptly and considering future medicines to extend your lifespan is allowed
I have always felt a little out of synch like I was born too early. Not sure I need longer than a regular lifespan, but might consider pausing. The problem is that I have friends, kids, brothers and sisters, don’t think it would be pleasant to wake up with all of them dead or old. So probably not.
