I'm 45. One of my good friends has a stutter. I met him randomly through my current job. There were always at least a few other people in my school that had a stutter. I had an acquaintance on my dorm floor in college who stuttered. I went to a stuttering camp at Ball State when I was in middle school. Everyone there had a stutter or something similar. So I've met or known several people throughout my life who have stuttered. I'm probably the one pulling the average so high 🤣
