I have been folding for about 10 years and I started folding in school in 6th or 7th grade. From there I worked up to folding every day in class in high school, but I didnt really fold outside of school. Every one of my teachers would have one outburst at me for folding during class, but then they settled down when they realized I was paying attention (for the most part).
Now I am folding every day and designing (or attempting to ) my own models.
Lately, I don't get to fold all that often. However, if I've got paper in my hands, I usually fold it without realizing, experimenting. I usually end up with some pretty weird shapes...
I only folded when I got put in a wheelchair for four weeks. Lol, that's the only reason I picked it up in the firstplace. I would say I fold about twice a week.
