Look at this beautiful old deserted quarry. Blue water, nature all around and - surprise - a rope swing. One can swing on the rope just like that, but one can also swing and jump into the water. Until he sees that the water is riddled with snakes. These snakes usually sliver into hiding as soon as they hear loud voices or feel human presence, but this fact still doesn't make most people swing and jump into the water.
Would you do it?
