so its your birthday,
have a great time,
i had trouble coming up with a silly rhyme,
so just go out n have some fun,
but dont eat too much,
and give yourself the runs....
That's 3 years left for you... on the other hand, the young man who sang "you don't wanna stay alive when you're twenty-five" is a celebrated 'old' rocker by now...
In other words - you got a whole career in front of you! cheers!
