That was me two years ago, gave it up after my head got friendly with the sidewalk!
I was astounded to see that "lunch" for the young construction workers in Dublin consisted of a Paddy, a Guinness, a Paddy and a Guinness. They then went out to their jackhammers once again. I was afraid to look down and see if any hobbled for lack of toes!
A fall from a bar stool is not so bad. A jackhammer on the ankle must smite a bit!
