I really Duked it out with a Co-worker on this one!!
(He's one of my friends, and an African-American

)
I said Yes. He said No.
Scientifically speaking here:My friend seems to be right!?
There is your "gut feeling", but thats not really instinctual by scientific standards and measures. More learned responses, experiences...
Animals have instincts to be sure! But do humans?
The 1 instinct I could find,and that was it, is an infants instinct to choke-up an object in their throat.
What do you think??
