Live forever but there’s a catch.
You get two options:
Reverse age. Option. A. Once you’ve reached age 75 or whatever age you like you take a simple growth hormone and it starts a process for which you will grow younger at the same pace as you are now only the other direction All the way unless you are injected with a anti hormone. Otherwise you would keep growing younger until you shrank and desolved into goo.
Artificial Womb. Option. B. You go into an incubator that mimics all the conditions that went into your birth except for a few details isolated in the process to keep you, you. However everything else is rebuilt, when you come out you are in premium condition forever. You’re stronger, faster and smarter than you ever been, but to maintain this superior state you can no longer eat regular food. No no you couldn’t eat enough energy before your organs burst to maintain this new body. You have to eat special diet of super food. Failure to do so and your new body will fall apart faster than you did previously with more pain. Oh and the food you need isn’t cheap.
So which would you choose?
Do you want to live forever for a price?
