it's gotta be the age. sometimes i wake up really really early (4am) and there's just no going back to sleep no matter how much i try. yesterday i tried something new. instead of trying to sleep i got up and went to bowen road for a run. i just walked from my apartment (about half an hour), about an hour's worth of jogging and walking (about 8km total, return), then another half an hour's walk back to my place.
