Well, I basically live without smell already, so that ones gone. I never could smell very well, it seems to be getting worse. Oh well...
I think I would have to say vision I couldn't go without. Though I don't know if I could last without music.....Hmmm....But music could only keep you excited for so long, if that's basically all you had. I think there are more forms of visual stimulation than aural, so Vision it is.
It would really suck having to live without a sense of touch too though.....
Bah! Let's all just count ourselves lucky for having any at all....
