Hmmm, nice idea but.......

"German scientists have developed a walking stick that calls for an ambulance if its owner falls over. The "i-Stick" detects if it is horizontal and plays a message telling the owner. If it is not picked up, a message goes to a control room, from where an ambulance is called."

If you could personalise the message played that would be cool... and interesting depending on who owned the walking stick...

i'm not dead yet...
