I would be 7"1. Primed for bad knees and being slow as drying paint, I probably wouldn't play any sport besides basketball, since my main asset is a good combo of speed/height. Doorways would be a issue, more of an issue then they are now for me. Ceiling fans would be the devil. Shower heads are already a large annoyance. Clothes would be custom fit, and expensive. I probably wouldn't live very long either.
please, 6"7 is already hard enough.
(Oh, and finding clothes at 6"5 is actually pretty easy Mikva)
