These videos test whether you have latent acrophobia

Personally, I don't like going up a ladder to clean the house gutters, so this video blew me away.  The first couple minutes inside the structure are o.k. - reminded me of walking up a forestry service fire tower.  But then he goes outside.  And after that, it gets worse.  And still worse.

Did you pass the test?  Then try this amateur video of insane Russian students climbing a similar tower with no safety equipment.  I won't tell you what happens at the end...
