You should learn to juggle. It's fun and can be relaxing once you learn. The kids would love it. I need to get back into it.
I'm really not up on all the latest technology. What we do at work is fairly specialist and some of it uses old stuff. I don't get to do much in the way of formal training, but I do enjoy learning. I did a few Coursera courses a while back on programming as well as some on music.
