I'm going to guess your age in just 7 steps.
1 - Choose a number from one to ten, for example, how many houses you want have?
2 - Multiply that number by 2
3 - Adds 5
4 - Multiply the number by 50, (yes, get the calculator)
5 - If it was your birthday this year, add 1760 ... If not, you've to add 1759
6 - Now subtract your birth year (4 digits) and add 1
7 - With the overall result have 3 or 4 digits. In the event that you choose a number from 1 to 9, the first digit of the result is the number chosen and the rest are your age. If you have 4 digits is becouse you chose to have 10 houses : )
