Swimming Lessons

January 19, 2016

I found a place between Christmas and New Year’s Day that was out of Internet reach. For four days and three nights I spent most of the days in the water looking downward into an ocean of coral canyons surrounded by swarms of colorful fish, and much of the nights on the open deck of a catamaran looking up at a nearly full moon moving between stars and swirling clouds. Here is some of what I learned from experiences, rather than from Google, on those days.

First, flying fish really do fly, on average, about the length of a football field.

Second, sea urchins have an edible element, if the spiny critters are smoked in a fire of coconuts and palm fronds and then soaked in saltwater, and if you are either desperately marooned on some remote island or just trying to be nice to the local residents you just met who believe the urchin's slimy, salty core is a delicacy that hospitality requires be shared and graciousness demands be appreciated.

And, more relevant to the work we share that I tried unsuccessfully to tune out for these four days, I learned ...

What you see in the ocean is distorted until you put on your goggles and get beneath the surface of the water. Getting beneath the surface of things is necessary for clear vision.

What you see first is likely to be the flashy fish, while the greater significance is observed more slowly in what appears to be their inanimate habitats, which turn out to be alive with movement if you wait and watch for it. Patience is necessary for clear vision.

The wavy six-inch line of purple coral was really the lips of a large clam that actually separate a fraction of an inch every minute or so to take in the nourishment of the sea. The brown stump below it was really a sea cucumber that actually moves an inch or two a day to vacuum the ocean floor. I saw none of this until I got beneath the surface, and waited.

A Hot Topic

It is a terrible irony that Georgia saw two of its high school football players die late last summer when it’s the Georgia High School Association that was providing us with the best information we’ve ever had about the risks of heat illness and death.

The deaths occurred in the third year of a thorough three-year study in Georgia that is reinforcing common sense. The study is confirming who is most at risk and when they’re most at risk.

  • Who is most at risk? Linemen more than other players; underclassmen more than older players; those who have had the flu or similar sickness more than others.
  • When are they most at risk? During the season’s first week more than the second. During the second practice of a double session day more than the first. During the second half of the second practice more than the first half, and, early in the morning when humidity is often highest.

It all makes perfect sense: the chubby 9th or 10th grader during the second half of the second practice during the first week of the season. And because it’s statistically predictable, heat illness is almost entirely preventable.

There is some danger here in over-generalizing and over-simplifying, but awareness of these tendencies will help coaches to schedule and administrators to legislate around high-risk scenarios. We expect both will be happening in Michigan.
