46. I started in college in my 20's when I took photography as an elective. Got hooked (having Keith Carter for my prof didn't hurt!). Stayed until I had my masters.
Now I infect young minds in the college classroom. Thanks to supportive administrators, we have a newly remodeled darkroom (from 7 to now 18 enlargers), larger classes that fill up, and new film users of all ages, but mostly in their early 20s.
