Physical fitness is the way to be fit both body and mind , believes Will Smith. The 'Men in Black' actor, who had to get in great shape for a number of film roles, thinks that a healthy body is equal to a healthy mind, reports China Daily.
"I feel like everything in my life depends on physical conditioning," Smith said.
I love eating sweets and everything, but I think the quality of my parenting, the quality of my relationship with my wife - it is all based on being on great physical condition.
"I believe it's the beginning of finding true happiness," he added.
