Right now I'm volunteering at a research facility, incubating tumour samples, turning the CO2 on white mice and watching them convulse and die, etc. If I have some off-time at work I play turn-based MMORPGs.
Follow that up with an 1.5-hour commute back home. Maybe stop by the library, sign out some art books. Go home, read a novel, eat dinner, 4ch, 4chan, a movie if there's time, sleep for 7 hours if I can manage it.
Eventually I'll have to focus on my studies if I want to get into med school. I just want this summer to be as easy and routine as possible.
