Not a big deal to me, as long as they are not continually telling me to run a mile and then put five shots in a two- inch group at 25 yards, knowing they can't do it.
The wise folks have been there and done that. I don't really care if they STILL can do it, I'm there for their wisdom not the show.
I agree with Coach's assessment about 100%.
I take a class based on their resume, experience, knowledge and mindset. All that comes from their past and keeping current with information. Keeping current in your physical condition, however, can easily be affected by life beyond being a full time operator like having a family, full time job, past injuries, and life commitments beyond worrying about how others think they look.
