The reason it works is because this year is 2014. And you know what:
" Minus the year u were born from [20]14......, you'll get your current age as the answer."
You said the answer right up there. It won't work next year, and heck it really doesn't even work now (if you subtract the year YOU were born from 114, I get -1869, that's how old you are apparently).
I would have thought that a 31 year old would be a little bit better at basic subtraction
