old timers say it puts lead in your pencil... that is what i was trying to say... In the days before Viagra and Cialis, old timers who smoked and drank whiskey and beer everyday used cider vinegar with mother every morning and with meals. I think it creates nitrous oxide in the blood which expands vessels and puts lead in the pencil... least ways that is what the old negro overseer at the camp told me as a child.
