NEED FOR SPEED
Back in my "young and foolish" phase as a controller in California, I practically lived on my motorcycle. One year at my flight physical the doctor said, "Oh, you must be a biker."
"How'd you know?" I said.
"You're heart. Bikers all have particularly healthy hearts."
I don't know what that was about, but apparently frequent elevated levels of adrenilan are good for you.
I agree, lots of controllers have a need for speed and a bit of risk - bikers, fliers and fast drivers.
