Junkie would refer to people who do blow,H, smack, meth...the hard "junk". People who need a hit at least 2 to 3 or more, times a day. Don't think alcoholic falls into that area. And the thing was, Draper 'was' a heavy drinker, not now. Cheap shot, really.
Remember seeing pictures, in some old IronMan magazines (when it was a great mag), of Pete G.. Back yes, but outstanding delts and shoulder width. And I don't think he was one of those dwarf BB'er, but around 6 foot or so.
