Don't do that you'll hurt yourself Don't do that its bad for your health I don't care cos I'm only young I don't care cos I'm having fun
I'll be happy to live till I'm twenty That I'll do me , that I'll be plenty Twenty years that's a lifetime Twenty years ill go in my prime
Twenty years that came around quick I'm still having fun and I don't feel sick Now that I've lasted this long I'm quiet sure I can hang on for at least twenty more
I'm forty now and surprise, surprise I feel as if I've just opened my eyes Who's in charge, Who's running the show Where are we heading, dose anyone know
How can I help with all my great knowledge Forty years of living, a couple at college I'll join a cause and I'll fight the good fight I'll just see if I can put things right
I never thought I'd make three score Now that I have I'm aiming for four Well why not, You never know matey Lots of people live till there eighty
Don't do that you'll hurt yourself Don't do that its bad for your health I don't care cause I'm really old and I don't have to do what I'm told
