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.

One Concussion Conclusion

August 25, 2017

After both the first and second years of collecting head injury reports from all Michigan High School Athletic Association member high schools for all practices and events in MHSAA sports, we cautioned people to refrain from making too many conclusions.

It’s too soon. We now have a baseline, but we will need several years before we can be certain that we’ve spotted trends or trouble spots.

Nevertheless, one observation screams out. Girls report two to three times the number of concussions that boys do. In basketball, soccer, and in softball compared to baseball, girls report two to three times as many concussions. That was true in year one; it remained true in year two.

It may be that girls sustain more concussions than boys, or that girls are more forthcoming in reporting than boys are, or both. In the past, researchers have published both conclusions.

In either case, it means we need to coach boys and girls differently, and we need to prepare coaches differently for boys and girls teams, as we are doing in the MHSAA Coaches Advancement Program.
