I'm 53 and if I wanted to go to beauty school, I'd go and wouldn't care if everyone else in class was 14.
Go, learn, enjoy, graduate, get a job doing something you like doing. No-brainer.
Same here. I'm 48 and I still think I might go to beauty school someday. I'm very interested in becoming an esthetician, and I don't feel too old for it.
I went to nursing school at 29...and I was FAR from being the oldest in my class (some of my classmates were in their upper 50's).
OP, you're never too old to learn.
