Oh ysy. Yet another disablist Writers' Block question. Not all of us have five senses. Sometimes I don't and sometimes I do.
I would most hate to lose my sight permanently but that is the one sense that is dwindling fastest, sadly.
The question I answered here, in case they change it (which they have done before), was, "'The five senses' are generally listed as hearing, sight, touch, smell and taste. If you had to give up one of these for a year, which would you choose?"
