I'd probably be jumping off of buildings and doing flips in the air like a superhero!

Save money on skydiving trips.

Still be afraid of heights probably

Probably fall over on my face a lot for the lolz

Do the wildest stunts in the worlds biggest cities across lines of LED lights through walls of skyscrapers

Be a better snowboarder

I'm finally realizing before I answer that I overthink this sort of question - my main problem here is that I'm trying to think of how whatever mechanism this was would differentiate "falling damage" with any other type of blunt-force trauma that might be inflicted on a body, and the only real difference is what is moving according to Earth's reference frame.

But enough of that: I'd clearly need to go to some city and make bets that I could beat people in races to the bottom of a tall building by just jumping down the center of a stairwell or something.
