Reflexes A very simple test of your reflexes! Wait for a fairly small red circle to appear on screen, then press the letter 'G' on the keyboard to see how fast you were. This is not a scientific test, however, it is accurate. Time reported back is in milliseconds (1/1000th of a second) and the quickest reflex time is recorded in a cookie so it is remembered for future visits. Resetting the best time will delete the cookie. Don't try to cheat - it won't let you! Test my reflexes     7 KB  |  Internet Explorer 4.0+ only. I bet you won't get below 200!
