How can anyone last on four hours a day?

I got six and a half hours of sleep last night and I'm so exhausted now that I can't think straight! I should not be this wiped for missing an hour and a half!

I was working on some logic homework, successfully completed the first problem, started on the next... and then my brain shut down completely. I finally gave up after an hour of staring at the paper. I'll try to finish tomorrow. (Someone make me, please! I've been putting off too much work as is!)
