Let me preface this blog with the fact that I am somewhat of a thrillseeker.  In fact, I'm about to skydive for my 5th time next month.  That being said...this video makes me have a borderline anxiety attack lol.  These two guys are INSANE!

Watch 2 Russian ninjas climb to the top of the Shanghai Tower, which is 2132 ft in the air.  And you can definitely tell from the video.

(**DO NOT TRY THIS AT HOME...if your home were 2132 ft high**)

Two words: In.  Sane.
