This guy has been floating around the net for a couple of years... he's even featured in a Stan Lee "Super-Humans" tv show for his ability.
It's remarkable but the guy has been doing it since he was a CHILD... for an adult to take up that type of training... and as Archangel said... doing that and carrying weaponry... uhh, good luck.
Again the Ninja myth crosses over to reality. Watching this guy and imagining him in an all black suit with head mask and all of that and seeing him infiltrate a secure complex to do some dirty deed isn't TRUE Ninja tactics... Hollywood yes, but reality ... no.
As a climber I admire the guy's skill level and agility.
As a practicing MA-ist... I fail to see the practicality.
