I'm physically disabled and breathe through a trach, a hole in my neck that has a plastic tube going down into my lungs, which in turn is connected to a vent.  Basically mechanically assisted breathing, but I live at home, I have the full use of all my limbs, and I'm typing everything myself, so I'm doing pretty good lol.  I was born with a rare form of Muscular Dystrophy, so my muscles are naturally weaker than most people's is all.
