What introduced you to swimming?

Out of curiosity, what brought you to swim? I'm a fitness swimmer now and do OW races for fun. I began swimming as an alternative to running, I had taken a swim class in college that demonstrated routines and corrected my form enough to do well without getting frustrated or feel intimidated. When I had trouble running I would go swim instead. I began swimming regularly to train for the Long beach triathlon years ago. Now I enjoy swimming just as much as running...it's a new challenge as well as a great stress release for me. I'm just finishing up my credential and will be transitioning from a career in IT to teaching, which means that i'll be open to joining a masters team soon! Wohoo! Here's the question.... Why did you start? When? What's your day job?
