And, somebody mentioned that sex with different people would feel the same because the body would respond in the same way, and the rest is in your head. The person who posted it appended this interesting and far-reaching conjecture with "presumably", so I concluded that the poster had not conducted any experiments to collect and interpret data to prove or disprove the theory, but used a seat of the pants approach instead.

OK, then in the seat of the pants approach fashion, can we theorize why the body responds differently to different foods and why we enjoy hearing different voices (I mean actual real voices of different people and not psychotic voices)? Is it due to some differences in the foods and the voices and our perceptions of them somehow mixed together or is it just completely "in your head"?

If it is completely in my head, I would like to receive some sort of nutritionally-balanced and affordable easily-preparable meal every day, just same stuff every day, and some therapy to help me deal with the fact that I have such strong preferences with respect to food and such a narrow range of acceptable choices and also get bored with the same tastes if they are repeated too often. I care about variety so much that I rotate the cat food because I feel compassion for the cats and assume that they, too, enjoy variety. And, I also very much enjoy the value the non-nutritional aspects of eating, say texture, smell, and general esthetics. So while I do want the easily-preparable meal and all the convenience benefits that come with it, someone would need to help me deal with this annoying habit of being so selective and particular.

Please let me know where I can get the food and the therapy.
