Unfortunately, I appear to be a small part of the population which has extra taste buds, and my sense of smell is extra sharp as well. It means that anything that I taste I can identify the ingredients in, and replicate if it's possible, and sometimes can identify obscure ingredients by smell alone. On the other hand, I can smell and taste the turning point of food, and everything else, before most people can detect it. That makes some things unpleasant to me, and not other people. Dh says that he wouldn't want to have my taste buds/sense of smell.
On the other hand, I agree on everything on your touching list. Absolutely. I touch everything, pretty much.
And, I have great textural memories. Such as a small pillow that I grew up with. It had a very textured surface that I can remember to this day.
Whenever someone gives me an object, and asks me to guess what it is, I handle it first. :-)
Love All Life, Thank You For Posting! :)
