Any postdocs here with a PhD in science/engineering working in London (at Imperial, UCL, etc?) What is your lifestyle like? With a postdoc salary of 30-40K, do you live in a shared flat near your university in Zone 1/2, or alone in a flat out in Zones 3+ ? What are your usual working hours? Do you often run experiments late in the evenings/night? If you are single with no children, how do you spend your weekends besides cooking/housework? Do you have to work/go to lab during weekends, or have time to enjoy going out to museums, theatres, meeting friends etc in London? How different is your life from being a PhD student?
