Why do kids us the companionway as a jogging track?

I have recently witnessed kids running into vacuum cleaners,
housekeeping trolleys and tripping over electric cords as a result of
non stop running in the hallways and waking up, those who are sleeping
in their cabins and suites.

The cruiselnes get sued when injuries occur, but do nothing to stem this
habit from the "make some noise" generation.

Any ideas????????????????
