Has anybody noticed...?

This cool math trick?
This is not one of those waste of time things, it’s fun. It takes less than a minute. Work this out as you read …
1. First of all, pick the number of times a week that you would like to have chocolate (more than once but less than 10)
2. Multiply this number by 2 (just to be bold)
3. Add 5
4. Multiply it by 50 — I’ll wait while you get the calculator
5. If you have already had your birthday this year add 1756 …. If you haven’t, add 1755.
6. 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!
Hehe, don’t be so surprised. You know, this is a math trick. You probably have entered enough information to calculate your age along the 6 steps.
