I firmly believe that snakes do in fact think logically, and remember things... if it is handled more and more, with time it comes to realize that you're not going to try to hurt it... thus, being able to consider it "tame". I do, however, believe that they hold onto those wild instincts... i.e... no matter how long you've had the snake, if it bites you because of a feeding mistake on your part or something and gets a good grip, odds are it ain't letting go.. just like anything it would bite in the wild. my 2 cents... which is probably not worth quite 2 cents...
