anyone who's vigilant knows what's going on and they're aware of what's happening, so again it, it shows that we must do something as they said on that motorway, the thing to do when you feel yourself going into drow drowsiness is, is stop the car perhaps, get out and have a walk round, do something, i know i, er in the past when i've felt myself going off to sleep in those situations, i've been pinching myself and, and really making yourself do something rather than just sitting there doing nothing, cos that's the way we just go off and get lowered into sleep and our lives are involved in this, we've read and heard about people that have gone to sleep on motorways haven't they?
