Anyway, for example the empire state building, which I guess is getting old. with all the ice that expands in the concrete and weathering, and the swaying, how don't parts crumble off? I guess glass or metal curtain walls are somewhat flexible materials and also have rubber gaskets between sections which allow movement, but masonry seems like it would crumble over time.
It's limestone. It's not a solid block attached to the building, but attached to the steel frame. It can flex so it won't break.
