OK, "we all know" there are five senses: sight, hearing, touch, taste, smell. There are common English words to describe the absence of only three of them: blind, deaf, and numb. Why don't we have words for the absence of the senses of taste and smell? I have a friend who has no sense of smell and one thing that's odd is there's no single word for it! Or is there? Does any of you know? Could the docs aBoard at least tell us the medical terms for smell-less and taste-less?
