Mens sana, corpore sano or whatever it is
“Our findings suggest that there is something about playing sport, even though a person may experience concussion, that may be beneficial for long-term cognitive outcomes,” Dr Matt Lennon, a researcher at the University of New South Wales, said. “While it may be that those who play sports have had access to better education and more resources, we controlled for these factors in the analysis, so that doesn’t explain the result. We hypothesise that there may be physical, social and long-term behavioural effects of sport that may make for healthier adults in late life.”
This is headed by the weird line:
Oxford and Harvard study finds no link between amateur concussions and long-term cognitive decline
Which isn’t what they found at all. The suggestion is that having played sport competitively, if amateurlyly, provides a long term health benefit to cognition greater than whatever damage might be done by a few low-end head knocks.
Which is not all that amazin’ a findin’. Interestin’, but not wholly amazin’.
