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.

Counting Concussions
December 9, 2016
Member high schools of the Michigan High School Athletic Association are in the second year of required reporting of concussions that occur during practices and contests in all levels of all sports served by the MHSAA. In year one there were 4,452 confirmed concussions reported. Less than two percent of almost 300,000 participants sustained a concussion, about half of which caused the student to be withheld from activity for between five and 15 days.
Not surprisingly, approximately half of the confirmed concussions were reported by Class A schools, which typically sponsor more sports and have larger squads than smaller schools. Class B schools provided almost 30 percent of the reports; Class C schools nearly 15 percent; and Class D schools less than six percent.
As we transition from fall to winter season, we can begin to make comparisons between years one and two of the mandated reporting. At this point, schools are reporting 1.6 percent fewer concussions this year than last.
This is surprising, because sideline personnel of member high schools have become more alert to the signs and symptoms of concussions. We anticipated that this would lead to more concussions being reported.
It is possible that these early stats are a sign of real progress in reducing head injuries in school sports. And, grabbing our attention most from the early reports is that 11-player football is reporting 3.9 percent fewer concussions as of Nov. 30, 2016 compared to the same week in 2015; and boys soccer is reporting 10.9 percent fewer than on the same date last year.
