42, Machine learning. I discovered Coursera for me and worked through a number of courses. People say that learning is getting more difficult as you get older, but so far it is getting easier for me. When I was younger I didn't have the patience to learn something if I had no immediate need for it. There were distractions everywhere. Now it is much easier for me to focus on a single thing.
