You don't need to tell kids not to try this shit at home. What difference does a "do not try this at home" written in 6 point size at the bottom of a man jumping of empire state building image going to make. Will it ever be noticed coupled with fact that there is more to read. These stunts have been performed by experts. Of coarse you cannot jump from empire state building being at home. so the argument is invalid. 2ndly they never tell you that the expert in question is an expert at what. they leave that part out, they don't put it there cause cannot have too much to be said because the viewer my friend has to read it and understand it. Are you telling me if we took out these warning signs out, there will be people jumping of, jumping into, driving into walls, bunjee jump, sky jump to get to bottle of cola. If we could ever so do that.... it would be best campaign ever designed to get people to be active. Nike are you listening.
