Well friend, it's like this...don't you ever wonder why some people just love chocolate ice cream and others swear by vanilla? There's still that oddball few who prefer strawberry over al the other flavors. Now, do you think in every case it was upbringing, bad experiences or religious upbringing that caused their particular preferences
Our minds and bodies differ, more often than not for reasons that can not be quantified or qualified. Just the nature of human beings.
Enjoy your flavors!
