That's messed up. The kid's a little psychopath. My son has a hamster. He gets excited about a new pet until he remembers that Cuddly has to die first and then he looks at me with pleading, tear filled eyes like I can get the hamster out of a natural end to his natural life. At that point, I drop it and change the subject. He won't even let me kill flies. Edited to add: Maybe his mother explains what happened so bad with him. Jeez, the one person who's supposed to stand between you and God Himself was trying to kill him.
Just imagine the world of being in a coma! A combination of memories, reality, and imagination all blurred into one! The infinite endless possibilities! Oh but how devastating it must be to return, especially if you remember anything! What you left behind, which you’ll never see again! Well, that’s if they don’t pull the plug on you!
Why would it fix his age / body? Of course it doesn’t make sense, it’s science fiction fantasy, it’s not actual fact. You need to make accommodations. For fantasy/movie logic, it makes enough sense to get by. If you were immortal, you’d probably enjoy being a boy, but you wouldn’t want to be a boy forever. Say I’m immortal - I don’t know what age to stop growing old at. I’ve had a good twenty years, but you’ve got to think about what age is going to be at the peak of physical fitness, and ability, and when decline kicks in, although I think we’re good for another decade. I couldn’t even legally rent a car until just recently. You have to think, between now and the year 3000, what age group is going to have the most options at self-development? Clearly, you don’t want to be stuck at 10 or 15 - every day of your life, people are going to walk up to you and ask you why you’re not in school. Be practical. I’d stop growing at maybe 25, 26, 27, something like that. Not like we “grow” at that age, we just accumulate oldness points. Sore joints, bad teeth, and glasses come with the next few decades, and pretty soon, you’re in a clinic getting your knees swapped out for bionic joints. No, thank-you!! I’d rather go back to being a little kid for the rest of my life. If it made sense, you’d know how you activate the “stop aging” part of immortality. Time still passes, but you don’t age anymore. It makes sense. It makes “movie sense”.
