Your Age by Chocolate

This is a fun little exercise that takes just a few minutes to complete.
Work it out as you read:

• "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 1756 ....
  If you haven't, add 1755.

• Now subtract the four digit year that 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.
