It will only work this year with the numbers you mentioned, it will work every year with the correct numbers in for the 1755/4
Its a very basic mathematical formula
x = number of drinks
Double it 2x
Add 5 2x+5
Mult by 50 100x+250
Add 1755 100x+2005
minus DOB 100x +(2005 - DOB) == 100x + Your Age!
the 100x basically shifts the decimal place two places to the right hence making the first of the three digits the one you started with, the other two are your age that is left over from the 2005-DOB bit.
YAWN!!!
