Gravity’s strength still an open question
The comments following this article are worth reading, too, although many are frustrating to any American who cares about the future of healthcare in their country.

"Executive Function", EF, describes how well our brains handle attention, self-control, working memory, problem solving, etc -- essentially, how our brains cognitively manage themselves. People with weak executive functions tend to have poorer health, higher crime rates, lower incomes, and generally more miserable lives than those who exhibit strong, effective EF. It's only recently that I have learned, to my surprise, of how much evidence there is that physical exercise strengthens cognitive EF!
Don't be put off by the dry title of this article, it's fascinating. What programs encourage the development of EF in children? Aerobic exercise is good, but Tae Kwon Do is even better. Classrooms run on the Montessori model encourage better Executive Function. And good old imaginative play with good friends may help the best:
