Yup, "Deep Thoughts" here in the Saturday-Night-Live sense. I was going to post something about creationism and political wedges, but I saw this CNN article about an injured male sea turtle beaching itself, and went deep.
Female sea turtles would add several dozen hours to the surface-living lifespan. That's not a deep thought, more of an aside. Just in case you're wondering.
