I'm starting this thread because I didn't want to highjack 419's post about Captain America. Instead of talking about Captain America in the comics or Chris Evans who plays him in MCU movies, I think the more important topic in this discussion is if it will be possible for a drug, or procedure, anything, realistically, in the future that could allow an adult body to continue to grow in synchrony. What are the potential obstacles we know of currently that might prevent this from happening? What are things that suggest it can be possible? For those who worry about their proportions, what problem(s) do you look for in this scenario where you now don't have to worry about proportions.
Also, if such a drug/procedure/whatever it may be, were to be accessible to everyone, and everyone in the world has gained 6 inches in height, would you be happy you're 6 inches taller, but still in the same standard deviation? For example if you are 5'6 and desperate for CLL currently, would you be happy being 6' tall now in a world where 6'3 is now the new 5'9 average? Are you chasing a number, maybe you want to be taller than everyone else, or for some other reason(s), would you be satisfied? Just some ideas I wanted to throw out there for discussion.
