Yep...you're way over the hill. Actually I'm joking.
I earned my MS in 1973 when I was 37 yo. Then I earned my PhD twenty years later, when I was 57 yo. It wasn't all book learning that was new either. I also learned how to downhill ski when I was 50 yo. And I joined an Antarctica expedition in 2005 when I was 69 yo.
I trust you get my point.
