I figure I'm about 20% behind..so at 41 I look about 32...when I reach 50 I'll look about 40..anti-oxidants,deprenyl,diet,exercise,no heavy bulking diets,I actaully eat relatively little for my size(~190,9%)...the most commonly accepted life extension technique is calorie restriction,albeit with enough nutrients..I eat "strategically" to resupply after workouts...I almost feel guilty if i eat and I haven't exercised..would like to get back to once a week day long fasts
