20 die falling out of bed
Who was it said, 'There are lies, there are dammed lies, and there are statistics'? (Oscar Wilde?)
Those 20 people were probably aged grannies, or drunken soldiers falling from three-high teir bunk-beds (I know of one who broke a pelvis doing this).
The three lads who've died falling from ladders while window cleaning - so far - this year would've probably not had more than a bruise from falling out of bed.
Most window cleaners are generally fit-healthy lads; so many things that kill the weak and aged don't apply.
