One can question the basic assumptions of the people doing the study described in “Sedentary off-hours link to Alzheimer’s.” One would hope that going to church is not less an intellectual endeavor than others, though it may be less physical than knitting or gardening. Even TV can be intellectual if viewers are testing their ability to stump the experts on a game show. This may be “a very intriguing study,” but it’s certainly not “rigorous.”
