When Are You Over the Hill? Try Age 24

Think you should worry about your brain slowing down post-age 50? Too late. It’s already started at age 24. Or at least that’s what a Canadian study of players of a hypercompetitive computer game has found. Apparently our cognitive motor skills – meaning the speed at which we process something and then react to it – peak by age 24, then begin to diminish slowly. But don’t be depressed! We make up for it by becoming more cunning and crafty, …

Is a Cold Mattress the Key to Better Sleep?

Are you hot in bed? No, no – not that kind of hot. (Although I’m sure you are.) I mean literally hot. Like sweaty, restless and unable to sleep well. A new survey by the Better Sleep Council found that disagreements about bedroom temperature topped tossing and turning and even snoring for the reasons couples gave for not getting a good night’s sleep.
