Lack of sleep?

Finally slept at a decent hour last night, but woke up way early. Yes, 3am! Don't know what to do but to go online and complain about this in my blog. The weather is getting warmer, but going to bed is still not as easy as used to be. I remember when I was 9 years old, I can fall asleep anytime anywhere. Maybe as people getting older, the chemicals that make you sleep diminish. No wonder people like my grandparents at their 80s go to bed way early and wake up way early everyday.
