I don't blame him one bit.
I'm retired and just turned 80. I'm the President of one amateur radio club and the VP of another. I'm also a member of ARES and participate in their activities regularly. I also edit and publish the newsletters of the two above clubs. I'm already beginning to dial back some of my ham radio activities. I recently resigned a section-level position, not so much because it took a lot of my time but because I was no longer interested in doing it. I've also, for all intents and purposes, dropped out of several ARES related nets.
Us old guys can't continue to do all the work. It's time for some of the youngsters to step up and seize the reins.
