Blindness cuts you off from things. You will no longer read the newspaper or your favorite books. You will no longer watch TV or use your computer (in quite the same way).

Deafness cuts you off from people. Except for a few or until you master lip reading, you will be unable to communicate with those you meet on the street, or in a bar, or in school, or wherever. Your circle of friends and acquantances will shrink to a tolerant and educated few, if any.

If anything it's a sign of my introverted nature that I'd probably choose to be deaf, though I would still have my music. The bass of good techno through good speakers sounds in my chest as well as my ears - I could give up one. I've been slowly realizing however that ultimately, being blind would be a healthier choice. I sometimes feel like I need every human that I can form a healthy relationship with to survive.

The potential loss of these two senses pales to what one could lose. If I lost my sense of touch, I think I'd kill myself before I went mad. I think touch is the most important sense.
