Postcard From Rio de Janiero

In Rio:

• A couple kiss in the ramp-up to World Bike Day, whose 6,000 riders are riding for better quality of life in the city.
• A five-foot-four girl cuts her five-foot-two hair. The reason? The $600-a-year shampoo cost and the hour and half it takes to brush.
• What to do with the indigenous squatters outside the city's stadiums.
• In honor of World Earth Day, the city's iconic hill-top statue goes dark for an hour.
