Yeah. I love really high heights - sky-diving, zip-lining, para-gliding etc... But I have a huge fear from about three feet up, like you say. One main reason I can't ride horses XD

I guess "fear-of-falling" works too but I find it funny because if you couldn't fall (Like literally COULD NOT - people just... stick to the air or whatever in this alternate reality), who would be afraid of heights?

Like I get way worried about short falls than situations where I'll probably die if I drop.
