Careful with that rubber duck: you might trigger a call to the paramedics.
The National Institute of Longevity Sciences in Japan says a laser embedded in
the ceiling of your bathroom could raise the alarm if you have a seizure or fall
in the bath. By bouncing a light beam off the water, a team led by Kazuki

鈥淭he system could detect if you stop breathing and raise the alarm,鈥� he says.
Not everyone is impressed: 鈥淭his probably isn鈥檛 the way you鈥檇 do it,鈥� says Dave
Delpy of University College Dublin. 鈥淚t sounds like overkill.鈥�
