First off, 160 lbs., a forty year old. I'm 6' 1" tall and weight in at 205 lbs (for those who would have problems, here's the metrics 1.8 meters tall, and about 90 kg), and I'm only 26.
Anyways, yeah, If I had to judge my strength by the D&D way, I would have to use two stats, upper body and lower body. My upper body would be about 12 or 13 and my lower body would have to be 15 to 16. My arms and shoulders are relativly weak while my legs are exceptionally strong (I was dunking a basketball when I was shorter and much younger 15 years old). At my best, my bench was 150 lbs., and that was 7 years ago, now I do good to handle 100-120. My legs in their heyday (there kinda beat up now) I could leg press about 900 lbs. max, haven't tried to see how much I do now. But my normal workout, 75 lbs. bench, 400 lbs. leg press. Realism and D&D would have a hard time statting me on strength, now constitution thats up there rarely get sick, never seriously injured, and my endurance (thanks to some good cardiovasular workouts recently) is really getting up there.
