Grandpa shot his first elk with a crossbow at age 93, public land. We had a guide and rode a sxs in, then hiked around 400 yards to the hunting spot. We packed it out for him. Still, we did that for a week and he came back next year for another one.
He would also go pheasant/grouse hunting with us, and sometimes alone. He would sneak up solo on ducks too if they were in a field. He stayed away from water when solo though because if he got stuck in the mud, he might fall or not get out.
At 87 he fell into a 3' deep hole, and at 90, off a 5' embankment when hunting with us. Also found lots of badger holes in the Dakotas. Luckily he knew how to fall. Even with only a few months to live due to cancer, he was talking about next hunting season 6 months away.
My great grandpa hunted/fished alone and with friends until age 89. He only slowed down because the boat trailer hitch fell on him and broke his foot.
Both may have moved slower as they years went on, but neither ever quit. Both were working into their 90's, never officially retiring. Point being, stay busy, keep going until the end. Both passed away in nursing homes but would have happily died in the field on one last hunt.
