...what would it be?
I think I'd like to lose the need to blink. That seems cool. I could really freak people out and they'd be like "I think Jack is half snake or something!"
Some people would probably choose the need to sleep, but I wouldn't. I mean, I can see why you would. You could get a lot of stuff done, and I think most people agree with me when I say that waking up on a school or work day isn't a very great feeling. However, if I didn't sleep, I wouldn't have dreams, and if I didn't have my dreams, I don't know how my personality would change. It would, though, I'm pretty sure. Also, napping is a very good feeling.
