Brazilian slackliners defy gravity with Sao Paulo's abandoned buildings

Stretched above the teeming megalopolis of Sao Paulo, slackliners are defying gravity via a Highline connected across the city's abandoned buildings. Slacklining is a sport that involves walking and balancing on a suspected length of flat webbing strung between two anchors. It's normally practised just shy of a few metres off the ground in local parks, but these local enthusiasts have taken it to new heights. Slacklining groups have become popular in Sao Paulo, providing Paulistas with a bit of respite from their day-to-day jobs. Slackliner aficionados say the sport gives them peace and balance in their lives.
