I'm sorry but it's very hard for me to take seriously Ben Franklin's exhortations to chastity and temperance. I guess he had some awareness of this given his famous dialogue with gout. http://www.bartleby.com/109/3.html
I doubt Ben took them seriously. He's well known for having fabricated popular stories on slow publication weeks/months. This was likely his form of click-bate.
Sure, we all fall short of our own ideals. But when your own lifestyle goes so far, gleefully, in the opposite direction you have to ask yourself if it's really a virtue you care about.
