We humans are social herd animals - we always seem to move in crowds and are never to far away from a fellow Mensch.

Especially during vacation time a modern paradox comes to light: we travel in huge crowds to ‘empty’ beaches to enjoy the ’silence’ and beauty of nature to recharge ourselves.

But neither a beach during vacation time nor airports are hardly relaxing environments. Add some screaming kids and your vacation is perfect. Or is this some form of "positive stress’ some people are talking about?
