I chose "sight", but I couldn't quite decide between sight and touch. I mean, I heard that blind people manage quite ok, but have you ever had your legs go dead? I really hate that! Or waking up and having no feeling in my arm. That's scary. Also you wouldn't notice if you've hurt yourself. So I think "sight" was the right decision.
About the other three: I love eating! So don't you dare take my taste away!

It's the same with smelling. I wouldn't have thought that so many people chose "smell". Smelling is very essential for me. For example the smell of good food when you're reeeaaallyyy hungry. ^^ The smell of rain, too ...
And hearing! That'd be the worst. I had blocked ears once. It was sooo bad! Drove me crazy ...
So I think it's "sight" after all.

I agree, though, that it'd be bad not to read manga anymore.
