I'd probably make a lousy player character in any genre, but in a fantasy setting, I think I'd be extra-useless. Yeah, I used to be a pretty competent fencer, back before my knees and ankles went south, but even in my prime, I had zero long-term endurance. I'm horribly near-sighted, and worst of all, I suffer from chronic migraines.
Unless the magic system works in a 32-bit Windows environment, I'm not going to be much of a wizard either.
(The above is what happens when I spend the entire day laid out on my back with a throbbing headache.)
