The main page video is of someone running and leaping along a narrow path on a precipice. There is a significant risk that they could trip or slip and fall. Such a fall would not be survivable.
They are not risking a fall with some possibility of death (or perhaps just a grazed knee), they are risking certain death. You fall, you die.
I have no idea what George Carlin's rant against the term "self-help" has to do with this, but it was pretty funny. So, thanks?
