I am going to look into if there is something "adjacent" that might be interesting to do.
That sounds a good idea. There are lots of online/remote/blended courses from all over the world. I'm sure UK universities would be quite happy to take your money.
It has been a long time since I have studied though!
Yeah, there's a lot to consider, especially because you have a family. I was thinking that this was a regret that doesn't need to be, though.
