How have your hobbies influenced your game?

One of my not-quite-obsessions in my youth was American coinage. I liked the history of it, the romance of it, the ways people “made do” with unofficial money during hard times (there are whole books and catalogs specializing in “Hard Times tokens” from the time of Pres. Jackson until the Civil War) or for merchants. [This has influenced me to enjoy the history and beauty of gambling chips, too. Did you know most “bawdy houses” had chips for gambling so customers had other ways to spend money in gold rush camps?] One result that has carried through to my game play even today is that I’m incredibly frugal with my chips.

Have your hobbies altered how you play? In what ways?
