I'm 79 years old and healthy. Was a 38-inch waist, but after losing some weight and having hernia surgery that significantly reduced the size of my stomach, I'm now down to about a 34-inch waist. I also shortened my pant length by two inches and bought new size 34 slacks.
The problem is that the new slacks keep sliding down. Even when I tighten my belt, it doesn't seem to help. And almost nothing in the pockets.
