With time, culture and thinking changes. When I retired ten years ago, I didn't understand what the younger folks were about and why went about doing things in the way they did. I have noted this phenomena in a number of areas of life.
I have noted that many shooters are concerned about dirty powder and lube smoke. Yes, my guns and hands get dirty and yes my lube smokes a bit, but neither were worth 2 second of my time to worry about. I just didn't care. I cleaned my guns, and washed my hands. I was concentrating at my target and never really noticed the lube smoke.
I am truly getting old and out of touch. I just give no thought, not concern to the issues that seems to get under the skin of the younger set. I suppose all of this should matter to me, but it just doesn't.
