Option A: Having normal vision. Glasses don't cover my whole visual range, and my eyelids are too small to use contacts regularly (I've spent as long as 25 minutes trying to get one contact in at times). Also, colorblindness is annoying, especially when you have an affinity for redheads. Option B: Complete limberness. Exercise and general movement would feel a hell of a lot better if I didn't need to stretch or pop my joints beforehand. Doesn't have to be on the level of a contortionist either.
