I'm in my 50s, but I'm learning to code, but I'm not exactly new to it. I just didn't do it for a long time and now it's a rather different world from doing Fortran on 110-baud Decwriters. I got into an electrical engineering program, but dropped out when I discovered that the number of times they let you fail differential equations is finite. I ended up with a career in publishing. No regrets, really, but now publishing like other businesses becomes increasingly high-tech (I remember editing with a red pencil and doing layouts with waxers and x-acto knives). I push xml files around and write xslt and xquery scripts. I wrote our code specs for our ebook program. Now I'm developing a python app to supplement the terrible proprietary inventory system we use.
I do not call myself an engineer.
