http://www.procrastinus.com/ link to "test your own procrastination level"

my score was 38/100. I am a moderate procrastinator...it did say I only answered 51 out of 100 possible shapes before exiting, but I didn't choose to exit...a glitch, or did my subconcious hit the exit button. Fastest reaction time 0.36 seconds. Slowest, 0.64 seconds.
