My screwed-up body clock

Since I moved to my current work, my body-clock was really messed-up. Being global does have a price and I don't know how much damage it did to my body. Well, I can still run at 5 am in the morning even without sleep but when I read the article sent by my former officemate, I think I need to think twice (not enough sleep = increase in the possibility of having a heart attack).

Well, I'm a nocturnal person and I'm more productive at night. But thinking about that article really changed my mind about my sleeping habits.

I need to do something soon... :(
