Man swims to work every day

Benjamin David was tired of the car traffic during his morning commute in Munich, Germany. So now he jumps into the Isar River and swims the two kilometres to his job. He packs his clothes, laptop, and phone in a waterproof floating bag.

"You kind of really are in a natural, almost wild river in a very urban context, so there's lots of green and pebbles and what not, kind of pebbly beaches, and that's where I start," David said.

"And once you get further into the city … it becomes more like a pool actually, the atmosphere, and there's beautiful historic buildings to the right and left of the river, and I just drift by those and enjoy the view."
