No doubt it’s coming. In my lifetime perhaps? I’m 61 now. Hope I still have the strength to help somehow.
I’m a couple of years older than you, but I still shoot very well and can hike 15 - 20 miles when I want to. So I say, if ever - now is fine. My biggest fear is for this to dribble on like it is and the real sh@t start when I’m in my 80’s.
