First of all, I salute you for still being active in the shooting and casting community at 80. I only hope that I can make it to where you are someday. I too, wish you were a neighbor. To visit and drink coffee together, maybe shoot a little, talk guns, ect.
Only you can decide the direction you want to take concerning guns and shooting. Some of your decision could depend on what family or friends that you have that have the same interest. If you sell off your guns and casting/loading equipment you can still enjoy the hobby through sites such as this one.
I wish you Good Luck with your decision.
