I am 76, when I was 67 I could still handle anything, almost. In the past 4 years arthritis has become a problem. My smoothbore 20 ga. weighs close to 8 lbs. and wears on my back at the end of the day. I drove a truck for a living and never worried about picking anything up until it got over 100 lbs. Now I struggle with a 40 lb. bag of dog food. In general we don't get stronger as we age.
