How many of us can remember, in the long ago far away, a time when we could run, backpack, ski or swim for hours? It slipped away from us a little at a time. We're Americans. We eat well. We drive everywhere. We got older, got busy, had families and a desk job. We are out of shape. Out of shape to the point we joke about it.
When you drive out to the range, park 25 feet from the shooting benches, and you're out of breath by the time you set up your rifle and spotting scope... When you stop shooting certain matches because you can't lay prone any more... When you, well you get the idea.
A lot of shooters practice as preparation. They have concealed carry permits. If there was ever a situation involving their family they would stand ready to provide the first line of defense. And they would, I'm sure, to the very best of their ability. I would, too.
So what if that defense involved running up two flights of stairs and
carrying someone back down and out of a building? Swimming out off a
beach into the surf to rescue a child or a grandchild? Grappling with a
mugger because you just left the school concert and you followed the
laws and put your carry piece in the safe before you left home?
Being able to hit a gnat in the nuts at 500 yards is a great skill to
have. But it's only one of the things we have to consider.
When I was in boot camp, we ran and worked out every day. We went to the range for 2 weeks and even then we ran and worked out every day. Even in the fleet, we ran and worked out almost every day, we went to the range once a year for a week. Our shooting time was overwhelmed by our workout time.
