It's never to late nor is anyone to old to learn. I went back and took financial and accounting classes at a local college just a couple of years ago in my 50's. It worked out very well as all the young adults were very polite; probably thought I was a professor!
My wife is a (retired) architect and yes it is a very male dominated profession. But hey, she's married to me so she can handle anything.
Our plans are to finish up here in Ohio, go and check the house in Vermont, then travel down the east coast surfing and sailing the first half of the summer. Then who knows? Maybe swing thru Utah and hike the parks in late summer early fall.
