You know those dreadfully obnoxious morning people who are chipper and ready to go first thing in the morning? The ones who might not even need coffee before they start singing in the shower? This bulldog is not one of those people. Scientists call our internal genetic clock our circadian rhythm. Our internal clocks are set for just about every 24 hours or so, although a longer cycle will cause you to tend to stay up late where a shorter cycle creates early risers. Sleep scientists studying the chronotypes (different time types) call the early risers "larks" and those who stay up late, "owls." The studies suggest that people with a late night tendancy might have better memories whereas morning people have fewer destructive habits. Night owls tend to think outside the box more, larks are more agreeable. Clearly, this dog is an owl.
