SFOTW: Don't Blink You'll Miss It

It is something that you never think about during the day. It just happens while you go about throughtout your day. I bet while you have been reading this blog you have done this a few times. Can you guess what it is??? It's blinking! And this week the sceince fact of the week is that average human blinks 4,200,000 times a year! What is your average number of blinks during a day? Have someone count how many times you blink for a minute, then multiply that by 60 (because there is 60 minutes in an hour), and then muliply that by 24 (24 hours in a day). thats the average number of times you blink during one day. TRY IT OUT!!
