People actually dive off the bridge in Mostar.  I listened in on an English tour, and they were explaining the bridge.  As if it wasn’t dangerous enough to jump off a bridge, you only have about 3 meters to land in the water and survive due to the shallow water and rocks.  Not to mention the very cold water.  You have to be trained to jump off the bridge and they actually have tv shows every year in Mostar to determine who is the best diver.  The people that dive off the bridge actually make it their job.  Tourists come up to them and pay them 50 Euros and they will jump.  Then they have a person walk around and collect tips.  Or you could pay 75 Euros and they will train you to jump.
