I've never had any life changing experiences or revelations that made me want reptiles...i was actually scared of snakes and such when i was a child. But as i grew older and the Discovery channel became available i started learning more and more, until i decided to buy my first one...
They are very intersteing animals and very fun to keep. That's the reason why i keep mine.
