pictograms drive me nuts. come to think about it most signs do. If public signs are any indication, the more we 'advance' as a civilization the stupider we apparently become. This one, to me, means to take heed as a man falling ass first might land on you. Or perhaps it means 'careful you might fall' which could be put anywhere we have gravity. There are signs in public washrooms telling people how to wash their hands. Is it just me or does this not indicate decline?

...it's probably just me
