My old man taught me how to use a heavy 1962 Swedish rifle, Kalashnikov 47 and colt 38 when I was 9, and he often said to me, "Someday you will be a man. No matter what your job then, there are some skills a man needs to learn. Use of firearms or bows and arrows to protect your family, skill to ride a horse or motorbike or drive a car so you can keep your family mobile when needed, and swimming to keep you afloat."
Being able to use firearms doesn't mean you have to use it if you have one (firearms is forbidden for general civilian here), but the point is you have to be able to protect yourself and your family the best you can.
