Tough question. At the moment it’s playing squash. Only just got into it in the last few months. Other than that I cycle a bit, visit friends, and in my holidays I like to travel. This year I plan to go America and Poland. I like watching live music (going to Glastonbury in the summer 🙂 ), and I perform stand-up comedy sometimes too.
It’s good to try and do lots of things that are different to science, to change things up a bit.
But yeah, if I had to choose just one thing right now it’d be squash. I’m playing against my supervisor (basically my boss) later this evening. We had a meeting earlier so I’m really keen to win!
