Trust me...I would LOVE to be a pilot, but due to the above, I would never pass my medical.
Hey, some blind guy in England passed his physical, so theres nothing that can hold you back

You just got to retrain your brain (thats what makes us more advanced than any other animal), I belive there was a conslusive study that stated that if you try something hard enough (no, not jump off a cliff and live, nothing of that sort) your brain will eventually find a way to do it. So I believe if you put yourself in some balance-intensive acitivies, you'll eventually get over it

I used to have a minor balance problem* too, but spinning in a spinny chair helped me get over that

*bike accident, went down a hill really really fast, and fell off...there were bells rining in my ear for like 2 days

I think you should go for it savas....(the only reason that I haven't picked up flying lessons is cuz my mom think that I'll kill myself....no idea where she got that from

)
