Think of how many times in the Week you feel like – wish eating some Chocolate, from 1 to 9

That number, multiply for 2 so becomes a par number (even)
To that number add 5
That number multiply for 50
If you already had your Birthday this Year 2009, add 1759
If your Birthday hasn’t come yet, add 1758
To the number minus the Year you were born (four digits)
The result is a 3 digits number.
The first number is the number of times you feel like eating Chocolate in a Week.
The next 2 numbers are… Your age. Gotcha.
The word is, 2009 is the only and unique Year for ever this will work,
Cool ah?!
