1. Vision - I wouldn't know what to do if I couldn't see. I'm really superficial, or I don't know. It would be maddening

2. Taste - I don't know if this is more important than vision, cause eating is a need. And we not only eat for need, but the food's taste is really important. It's like people that have cancer and have to be treated with chemotherapies, I think they kinda loose this sense and I can imagine that it's painful to have to eat but without knowing how does the food you're eating tastes.

3. Hearing - Music, basically.

4. Smell - It's the complementary of taste.

5. Touch - Bleh.
