“It’s commonplace to find people who look old at forty, or young at sixty. The reason isn’t the number of little wrinkles that may be sprouting, but in the way they use their bodies. 'Old' people have lost their flexibility. Their joints stiffen up from lack of use. Their capillaries constrict and less blood comes through to the tissues. That means the complexion is undernourished, too. And everything starts to taper off. When they stop moving vigorously they slow down mentally. They’re old in their minds even when they’re still on the happy side of middle age. And it shows!”
