Lifetime of Learning Might Thwart Dementia
A lifetime engaging in intellectually stimulating pursuits may significantly lower your risk for dementia in your golden years, new research suggests.
Even people with relatively low educational and professional achievements can gain protection against late-life dementia if they adopt a mentally stimulating lifestyle – reading and playing music and games, for example – by the time they enter middle-age, the new study contended.
“In terms of preventing cognitive [mental] impairment, education and occupation are important,” said study lead author Prashanthi Vemuri, an assistant professor of radiology at the Mayo Clinic and Foundation in Rochester, Minn. “But so is intellectually stimulating activity during mid- to late life,” she added.
“It looks like the bottom-line is that it’s never too late to exercise your brain, and that is good news,” Vemuri said.

Exercise
Twenty children were playing hide and seek in the park yesterday, with their teacher who counted to thirty before setting out to find them.
Of the total number of children, two fifths were boys and the rest girls. Three-quarters of the boys wore yellow jumpers, as did half of the girls. Of those remaining, half of the boys and half of the girls wore green jumpers, and every other child wore a blue jumper.
Half of the number of children in blue jumpers were found in under five minutes, as were half of the boys in yellow jumpers and two girls in green jumpers. Their teacher took longer than five minutes to find the rest of the children.
How many children took more than five minutes to be found by the teacher?
