wait a second, I may be stupid or I see an inconsistency. It said that the 5 with MS were unaffected by the disease. But if they were in cryostasis how would they know? The only way is if others in cryostasis without MS died. But then if that's true, how did normal men still survive in cryostasis? I guess it technically just slowed down their death but still. Also, more than 5 people in the world have MS so what about them?
There's a few holes I think might be filled by some logic but I don't wanna type more.
