Yup. When I was in my 20s, all these guys I knew in their late 30s and up were all getting up at the crack of dawn to go running or other activities. Seemed like they must be very disciplined. At around age 37, I started noticing I could wake up at 6am no problem, and now I could probably get up at 5 fairly easily, provided I can get to bed on time.
