If 'insanity' were a brand, Marc Busch would be its face, and he proves it in this video. <br /><br />Watch as Marc shows that fear is nothing but a state of mind by sliding down a mid-rise building and making it look as easy as turning off a switch. <br /><br />"It took me about 30 minutes to prepare for this descent," the subject revealed to WooGlobe. "I checked every level individually and made sure everything was safe and had a perfect amount of grip. I did the slides at the bottom first and slowly made my way up."<br /><br />He further stated that his biggest challenge was calming his mind down and trusting his 15 years of parkour experience.<br /><br />"After that, it was pure fun, especially the last long slide," he added.<br />Location: Lisbon, Portugal<br /> <br />WooGlobe Ref : WGA158604<br />For licensing and to use this video, please email licensing@wooglobe.com
