Since the days of the ancient #Greeks, it has been a widely held belief that athletes should sleep alone before any type of sporting competition, for fear it could harm their athletic performance.

Yet #Roger #Federer, whom many consider the greatest male #Tennis player of all time, with 20 #GrandSlam titles, has one concrete rule in life: he must share a bed with his wife.

“I refuse to leave the bed with my wife,” he says today in an interview in The Sunday Times Magazine. “[I say,] ‘We always wanted to have kids, but my dream was to be with you and not in another bedroom on another floor’. I’d rather sleep with kids screaming than away from my wife.”
