“A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.” R.A.Heinlein

My dear Exes Uncle was an Italian Stone mason. He must have built a thousand miles of stone walls in his life time, dry laid and cement bound.

Talking to him I never realized the dynamics involved in a stone wall. There is more to a stone wall than one rock piled on another.
