I know a guy named Tuna, not that it's relevant to anything, other than I am surrounded by tuna.
I watched the tuna schooling around the ship again, today. They are a brilliant, electric silver-blue that looks fantastic in contrast to the deep blue of the ocean. There are literally tens of thousands schooled up around the ship, endlessly cruising in a circle around the hull.
I've had this theory about my ability to sleep onboard and what affects it. One of the issues is incline. NASA uses incline to study the effects of weightlessness. I've checked the meters that track the pitch, roll and heave of the ship. I'm sleeping head down at an average of 2-4 degrees. A hard look at the drink dispenser in the mess confirms this-it has a clear, plastic reservoir that illustrates the pitch, roll and heave nicely, when filled with a colorful juice or whatnot. Hard science, people. The juice never lies.
Anyway, I think I need to switch my sleeping direction head to foot and alleviate the blood pooling in my head 4-5 hours/night. That cannot be good, can it?
