all senses are linked, losing any one would affect the others in some way (think daredevil . . .) and it has been discovered that there are quite a few other senses apart from the five we learn about in school, Thermoception, Balance and acceleration, Proprioception and Nociception are some I've just read up on on wikipedia.
If I could do without any of the main five senses, it would probably have to be smell, but if I had a choice of any of them I wouldn't mind losing my sense of pain (nociception). dangerous to not know if I'm injured or not, but I can always shout 'I feel nothing . . . NOTHING!' when I'm feeling down.
