Most days I work at least 8 hours. Some days I work a bit shorter, and many days I work 10 hours or more. Sometimes I even work on the weekends as well. Its not the most healthy work-life balance, but sometimes I am just so excited see what the results of my experiments will be, that I just can’t not work.
It depends – if I have a deadline, or if I am waiting for a machine to finish running, then the longest Ive stayed in one day is about 10 hours. My average is about 7 (including lunch!), but if I can leave early then I will – all work and no play makes Lewis a dull boy!
