Safety is a concern but everything that involves guns, knives, steep mountains, slick rocks and tripping sticks, getting lost or injured is a safety concern - like all hobbies/sports, that is just the risk you accept for being able to do something you enjoy and love. So, it all comes down to having the physical and mental ability to continue do it. Although, for me, if I lose my mental ability (Dementia/Alzheimer's), I told my wife to just drive me out into the woods in the winter to go hunting and leave me.
