When I used to go boxing, I used to come home absolutely shattered, and we did alot of exercise there, I'd stay awake 'til I went to bed, and zonked out straight away, so I'd say get active through the day.

Not only does it help you sleep, it is good for you!

I usually just play my GBA and listen to my ipod while texting five different people sounds like it would keep you awake but it puts me to sleep pretty quickly. Of course then I wake up with 3 of my most used electronics out of batteries

There are 2 movies I've seen that make it almost impossible for me to stay awake. not that they're necessarily bad movies, but something about the soundtrack and the editing style makes me very sleepy.

1. Inland Empire
2. Al Final del Espectro

You're strange... For me, playing the DS late at night pretty much equals "why my alarm clock's ringing at this hou - *looks* Oh craap...".

On top of running twice a day, swimming, lifting weights, and mowing lawns, I've started doing mixed martial arts, and it's killing me worse than those other activities combined.

I drop dead on the couch as soon as I get home.
