My oldest son has it. He bends forward and doesn't look quite his proper height. He was very athletic and played a lot of sports (for a fairly small guy). The worst comment be got was from his drill sergeant at Fort Leonard Wood.

They were in formation and the Sergeant yelled "stand up straight ________, do you have scoliosis or something?
My son replied, "Yes Drill Sergeant."
Sergeant said, "private, you don't even know what that is."
Son replied, "It's curvature of the spine Drill Sergeant."
So the Drill Sergeant replied, "Well, I guess if God screwed you up there's nothing we can do about it."

My wife also has it, as does several of her sisters.
