Learning new stuff gets tougher as you age. Fewer of the old neurons firing or something. I don’t understand the mechanics, but I know it’s true. Right now I’m trying to learn cartography in Spanish. El Instituto Nacional de Estadistica y Geografia in Mexico has been more than patient with my rudimentary Spanish and extremely helpful, but it’s an uphill battle. Accumulating historic maps is an equal and related challenge. My latest find is an 1887 map of Arizona and New Mexico Territories.
