No cause for alarm

I do not profess to know how or why it works but I had heard or read somewhere that your car alarm remote would have a greater effective reach if you held it to your head. Sure. Well this morning as I stood in the rain, on the median strip, waiting for the traffic to calm so I could finish crossing the road to the car, I thought "wouldn't it be good if I could turn off the alarm from here". Tried it from the normal position. Nothing. So what did I have to lose - except possibly a little dignity by looking like a silly person holding the remote to my head - but, behold, it worked! And I was suitably surprised - and humbled - by a very tangible example of science at work.
