I actually mostly work from 8 – 5 in weekdays, so I have my evenings free almost all of the time, plus weekends. I do a lot of things really, I like to go out on day trips to nice places that i can photograph, or go to the cinema, or have nights out.
I’m about as busy as most people working in full time jobs. Since I have a young son at home most free time is spent with him, playing or going to the park or the beach. Before he came along I liked walking in the countryside and reading.
I work from 9-5.30, and depending on whether something urgent is on (like answering IAS questions!) I work later during the day. At the moment, I don’T get out much in the evenings because I need to look after my daugher, so I tend to cook and read.
At the moment I don’t get that much free time because I have to answer lots of questions for this!
But usually I get lots of free time – one of the good things about being a theoretical scientist is that I can organise my own time. My boss doesn’t mind when I do my work if it gets done. This is great because I can take time off more or less when I like, as long as I make up the work some other time. But it does mean I have to be disciplined because the temptation is always to take off lots and lots of time and never do any work, which would be a disaster!
