Wouldn't Mind Losing my Hearing.

Pick a sense you feel like you would be okay with living without.

[Death's Spook]

My taste (not smell-disguised-as-taste, actual taste). It would have the fewest consequences, especially since it wouldn't affect a lot of what I think is taste (but is actually smell) and it would not affect my ability to perceive texture.

Plus, it would allow me to eat a ghost pepper casually.

Same with Spook, I think I could forgo taste and be totally fine. It's definitely one of the senses we use the least, whereas losing something like hearing or sight would just be awful.

Besides, losing taste would give you more reason to eat more veggies and less ice cream. I always found it strange how the stuff that's terrible for our health tastes great and the stuff that's actually healthy is very bland and flavorless.

smell, my sence of smell is already pretty weak so i dont think i'd mind the last bit buggering off too much

[Dragon Master Mike]

I would choose smell for sure. This is under the assumption though that my taste wasn't affected, and realistically speaking, it probably would be. I have a really good sense of smell and taste, but those two are the only ones that I feel like someone could live without and not have a problem.

Proprioception Well, since we're talking about the 5 senses we were taught in elementary school (see also: the boring ones), I could probably do without smell. Aside from the occasional death by toxic gas, I already have a pretty bad sense of smell and could do without it.

Oh man....it's hard to choose even one. I mean so many I feel like it would be drastic to live without. My eyesight isn't the best and I fear ever losing that. Same with hearing. I love just how great my hearing is (seriously it's like a curse at times too. People can't listen to music too loud here xD). I love being able to taste and smell. Touch is kind of important too. I guess taste, because one. You can eat anything and not care if it tastes bad or not. A veggie hater could suddenly eat healthy lol. It's kinda of something to be careful of too though. You couldn't just go eating tons of ghost peppers. That'd be dangerous. So I guess the best would be taste, but good smells would be pretty taunting.

Maybe I'll actually eat more vegetables and be healthier if I went without taste. xD I don't think I'd want to lose anything else.

[Noblejanobii]

I'll be honest. I'd go with smell. I don't think I ever really use it at all since I never stop to smell the roses amor anything. It'd actually be more useful to lose it because then when I go through school I don't have to smell the combo of perfume, lotion, axe, and BO. I use all my other senses, including taste, quite often, but not smell.

Definitely taste for me. I have a friend who was born without a sense of smell and I know that his taste is affected. So, if you lose your sense of smell, you'll lose some of your ability to taste fully, too.
