I think I would rather go without brushing my teeth. Besides the grime that would build up, I need a shower to wake up in the morning. And if you wash your mouth out enough times and eat gum, it would be kind of bearable I think.
Edit: didn't realise the topic had just been changed.
Tough one but blind, I guess - I've had almost 30 yrs of sight so it's not like I've never experienced it, and obviously, I would not be able to do without music so I would not want to be deaf.
Partial blindness runs in my family. I don't have the gene, but I think I'm more sympathetic to blind people for that reason. So probably blind just because I've already seen the world, and I would hate to not be able to listen to music or talk to people.
Deaf. Its a hard one since both would ruin films and television shows, but bein able to watch them would be better than just listenin. Plus I wouldn't be able to play video games or draw if I was blind.
