Improving Concussion Data

August 18, 2017

The Michigan High School Athletic Association’s 750 member high schools reported nearly 500 fewer concussions for the 2016-17 school year than the year before – 11 percent fewer.

That’s good news, but it’s not a trend we can bank on. It’s too soon to do that. There are too many variables that might explain or contribute to the decline from 4,452 to 3,958 concussions.

But of this we are certain: Schools are taking head injuries seriously. It is not a lack of concern or a lack of care in reporting that has led to the 11 percent decline.

It’s more likely the second year’s data is just better than the first year. The process was better understood. The numbers are more accurate.

Our data will become most reliable and useful when we have several years to compare and analyze. Only then will we really know where the trouble spots remain; and only then can those areas be most effectively addressed.

Patience

January 20, 2015

I found it amazing that an important "test" match in cricket last month between India and Australia was scheduled for three days but could last five days, or might end after two. This flexible scheduling is just part of the game.
On one day of that match, Australia was able to bat all morning, declare a lunch break, and then keep batting most of the afternoon before India ever had an opportunity to go on offense. When they finally did, India was already behind 400 and something to zero.
It was equally intriguing to watch the fastest two of the 117 yachts entered in the 70th Sydney to Hobart Yacht Race finish the more than 628-nautical mile course within 48 minutes of each other, but 11 hours before the third place yacht. And, two days before the last of the 103 finishers. 
I decided that Australian sports fans must have a different definition of drama, a lot more patience for events of long duration, and much more tolerance for events of indefinite length than we do in the USA. Perhaps it is in the DNA of Australians to be patient ... for they are certainly among the most polite populations I've encountered.
Perhaps all of this is inherent in the character of a country that is almost as large as the USA’s first 48 states but has only seven percent of the USA’s population. In fact, China's population increases each year by more people than the total population of Australia ... which may have something to do with 36 people being killed during a human stampede in Shanghai this past New Year’s Eve.
