When I was a kid and I'd visit my Dad he always had 'pop' around, and it was just something we'd power through without thinking. I'm not sure if I even thought that it was bad for me in a concrete way. It was just super sweet and felt 'fun'.

When I was 19 I worked at a tech company with unlimited pop available. The 15lbs of additional weight caused me to look at it a whole different way, and broke that habit pretty fast!

Now the only time I have Coke is after a huge endurance event, otherwise it's just way too much.
