I can't imagine how annoying life would be if I was Marty Champs height. From sleeping to taking a piss/dump to having to eat more food & taking more PEDs... hell no. Sounds like torture. I guess they get used to it.
Imagine having to either tuck your knees up in bed like a fetus or having your feet/legs hang over the edge of the bed every night 
No thanks. Would rather be Darren A's height in da cage!
Thing is, you're not lengthening your upper body with this method, just breaking the legs.
Let's say you go from 5'11 or 6'0 to Martys height
Upperbody is the same, but now you have ostrich legs instead.
Someone would be a fool to be trying to replicate Marty Champs senses. (would always smell paint thinner)
