You're Weightless, You Know, It's All Real

I think your video was got to be right up there. It gives people much more of a visceral, intuitive feel for what it would be like for them to be living on a spaceship.

Your sinuses are always kind of clogged up. You got to sort of reteach yourself how to play guitar. But it made it easier to hit the high notes just because of the physiological changes going on.
