It's interesting the parallels between us. I'm about 40 and sleep 5-6 hours a night. Never tired during the day, never drink caffeine (ironically, I sometimes drink it in the morning in hopes I'll crash and fall asleep). I do an enormous amount of cardio, on bikes! It's 1:17am for me. I will be awake for another hour most likely. I'll get up before 8am and ride for a few hours. Never a yawn. It's really fascinating and I have no idea how to explain it.
