Any thing that controls your life in a negative way is sin. For some 1 beer is to many. For those to drink is a sin. Some people cannot control their lust, and thus it rules their life and is a sin. Some people's lives are ruled solely by $$, and thus greed is a sin. That does not mean for any one to drink a few beers, enjoy sex, and want to save a few bucks is a sin. I believe that any thing in excess can be sinful. Seek moderation and follow the ten commandments, which by the way are good thinmgs to do anyway.
