some of you wont know what I'm talking about here. Others definitely will because it came up in a thread alley posted many moons ago about weird things that give you good feelings and it got a few responses. I don't know anyone in real life that gets it though.

So basically, some people get this crazy good feeling in their head/neck area in response to either or both:

(a) someone speaking/ whispering at a certain frequency
(b) watching someone do something very methodical and slow, like doing ironing

I get it entirely in the neck and only from (a). I want to know what the hell it is, how it's triggered and why we have it. Thoughts?
