I am so awesome, I counted in my Biology exam.
Yes, counted.
I 'finished' early (I was flunking Biology at the end of the semester) and I was bored, so I started counting. I counted to 100...
45 times. Yes. I counted to 100, 45 times. Thats 4500. And to make it better I counted 1 a second, so thats 4500 seconds I was counting. Working that out, its 75 minutes, or 1 hour and 15 minutes.

I counted for 1 hour and 15 minutes straight.
