I took a double major in Economics and History in college in the 1970s. My "sweet spot" probably lies at the intersection of those two subjects. For instance, "Don't fire until you see the whites of their eyes" was really an "economic" admonition--to conserve ammunition.
I am the published author of "A Modern Approach to Graham and Dodd Investing" (Wiley, 2004), an (economic) "history of the future," and the unpublished author of "Axis Overstretch," an economic analysis of World War II.I
