Seriously, I wouldn’t want to give any of them up. Each one of them is a gift, and each one provides a fundamentally different aspect of life’s perception. I don’t care how sharp I could have another sense, I just done see how it could truly compensate for the sense that was lost. Okay fine, I realize that the purpose of the prompt is to make up my mind about that. I guess I would give up smell. Of all the senses it is probably the least useful. While there are many pleasures that can be experienced only via smell, there are just as many crippling stenches. The sense I would enhance is an easy one: sight. My eyesight was 20/70 at the time of my last checkup and it is only getting worse. So if I had super sight I would be a super human. Who wouldn’t want to be that?
