Daredevil climber's brain shows no fear during extreme stunts: Experts reveal why

U.S. professional rock climber Alex Honnold upped the ante during his recent urban climb in Taiwan. 

The daredevil athlete scaled the Taipei 101 skyscraper on Jan. 25 with no ropes or protective equipment. The event was streamed live on Netflix, as Fox News Digital previously reported.

Honnold successfully reached the summit of the 101-story steel building in just an hour and 31 minutes, waving his arms in victory at the top. He later noted the view was "amazing," even though it was windy.
