This takes less than a minute…Here goes:
Don't tell me your age  you probably would tell a falsehood anyway
 but the Hershey Man will know your age by Chocolate Math.
Work this out as you read.
DON'T CHEAT BY SCROLLING DOWN FIRST!
This is not one of those wasteoftime things, it's fun.

First of all, pick the number of times a week that you would like to have chocolate (more than once but less than 10).

Multiply this number by 2 (just to be bold).

Add 5

Multiply it by 50  I'll wait while you get the calculator.

If you have already had your birthday this year add 1759… If you haven't, add 1758.

Now subtract the four digit year in which you were born.
You should have a three digit number: ___ ___ ___
The first digit of this was your original number (i.e., how many times you want to have chocolate each week).
The next two numbers are… YOUR AGE! (Oh YES, it IS!!!!!)
THIS IS THE ONLY YEAR (2009) IT WILL EVER WORK, SO SPREAD IT AROUND WHILE IT LASTS.
Now….how does it work?
