Humans use nerves in complex ways to detect, transmit, and interpret signals of texture. Consider the range of sensitivity in the population -- some people wear lace because it's fashionable, others have to cut tags out of clothing. As I have pointed out many times in the past, this may not be a mental difference at all; it could be physical. Likely it's a combination of both. We can only influence the mental aspect; we can't really make a body have more or fewer neurons, and we can only influence their behavior somewhat through indirect methods. Often it makes more sense to modify the environment instead: thank you, people who invented silkscreened tagless t-shirts.
