1. How often do you think about chocolate per week?? (must be a number higher than 0 en less than 10)
2. Multiply this number by 2
3. Add 5
4. Multiply this number by 50 ( I will wait while you turn on the calculator)
5. If you have already had your birthday in 2007 then add 1757. If you haven't had your birthday yet in 2007 then add 1756.
6. Subtract your year of birth (4 numbers)
7. you are left with 3 numbers. The first number is how often you think about chocolate per week and the last 2 numbers is you age.
(2007 is the only year that this sum works)

This could work for anything, and it's not all that mysterious.
The formula is:
50(2n + 5) + 1756 - b
where n is the number you started with, and b is the year you were born.
This simplifies to:
100n + 2006 - b
So it's a bit clearer now that the 100s digit will be the number between 1 and 10, and the second part gives the years since your birth year.
Of course, if you think about chocoloate 5 times in two weeks, say on average 2.5 times per week, it will guess your age wrong
And if you think about chocoloate more than 10 times per week, provided it is an integer number of times, it will still work.
Maths Rules!
