I love how derpy that picture is. ScienceDaily ftw.
Anyway, I think the circadian rhythm is incredibly fascinating, so I was excited to read this this morning.
"The body is essentially a collection of clocks"…”We roughly knew what mechanism told the clock to wind down at night, but we didn’t know what activated us again in the morning. Now that we’ve found it, we can explore more deeply how our biological clocks malfunction as we get older and develop chronic illness.”
