My own sense of smell
has been corrupted and reduced by too many years of tobacco usage, not to mention the polluted airs. I still function fully with civilization, despite that smell de-sensivity.
But if I were not able to touch/feel the world around me I would become a basketcase... there have been experiments done upon infants that were not touched and they were at a loss of what makes humans what they are... anti-social and fearful of other humans.
But I will not refute the importance of a good sense of smell no more than any other sense... they are all wonderful and life-inspiring, but not as vital as touch/feel to complete the life experience.
