 People want to explain what's happening now and they want the reasons. Why is the world like this? Why is this thing happened? And those were the questions that really started coming up. And so I ended up doing far more recent history than I'd ever studied. And really, for me, kind of centering on the Cold War as a period. That's where I really started out. And that was partly because it was within recent memory. It was quite close by, but it also sort of seemed to explain so much of our world around us.
