“There are also many important grounds of health in favour of nudity in suitable circumstances, such as out-of-doors in sunny weather. Sunshine on the bare skin has an exceedingly health-giving effect. Moreover anyone who has watched children running about in the open-air without their clothes must have been struck by the fact that they hold themselves much better and move more freely and more gracefully than when they are dressed. The same thing is true of grown-up people. The proper place for nudity is out-of-doors in the sunshine and in the water.” —Bertrand Russell
