It’s a cloudy morning in Busan, another in string of dreary, cool days, but at least I’m up to enjoy it. One of the pluses of my recent motorcycle wreck and subsequent hospitalization is that my sleep schedule has shifted. For the first time in life I can count myself as an early bird, though I doubt this distinction will hold after I’m up and moving 100 percent. Like my mother, I have always been a decidedly nocturnal creature. I am convinced that such proclivities course through our veins, that they’re buried deep in our DNA.
