Advanced Calculation
Here's an interesting mathematical equation that someone sent me the other day:
Pick up a calculator and consecutively enter the numbers of your birthday.
Add 754.
Subtract 753.
Add 1.
Now, divide this number by yesterday's date and add 59 to the total.
Subtract 59.
Add the number of fingers on your right hand.
Subtract the number of toes on your left foot.
Divide this by any number between one and ten.
Is the number you came up with your age? No? Dang. Oh well. It didn't work for me either but if it had it would have been pretty cool, wouldn't it?

Revolution
Five-years-old seems to be an age where a child will rebel against the word "no." I know my son knows what the word means because, when told "no," he will respond by saying "no." I have no idea where he gets this trait. It must be something he has picked up from school.
