Those of us who are one the far side of 70 years, should take encouragement from shooters in the game like those mentioned in the title and others, who prove shoot after shoot that age is not a barrier to participation and being competitive in this game. At my own club, in our group of shooters, five are in their 80s, and still going strong. A good lesson for shooting, and in life. Keep moving.
I just turned 79 and can still shoot great scores when my sciatica is not bothering me. I just had epidural injections and am getting m 2d set on Dec 12. It is really helping as I am almost pain free.
I sit in a chair while shooting with sciatica pain. One injection so far with mixed results. At least I'm still shooting and not too bad.
