This isn't necessarily age-related - people at all ages need to be back upright, and ideally back walking on their own feet, as soon as possible again. I've got a planned surgery coming up in february (I'm 23), and despite it being a major surgery, part of the recovery process is that I'll have to be able to stand upright - even if just for a few minutes per day - already on the first day after surgery. This is also why, if you absolutely have to stay in bed, you should use the remote for your hospital bed to at least sit in bed for as much time as possible (and why you should buy beds which have such a mode at home, too)
