I've been up to the Whittington a few times lately and this sign ""Clean Hands save lives" is writ large evereywhere. And it's not true. Dirty hands spread disease is true. Cleanliness and hygiene go together, and good health follows. But clean hands do not save lives. Defibrillators save lives, antibiotics save lives, scalpels skilfully wielded save lives. But Clean hands do not.
And anyway all they are trying to do is to get you to wipe alcohol gel on your hands after which your hands may be sterile, but no cleaner than they were before. If you've been to the lavatory, not washed yours hands and emerged with traces of non-sterile waste products onthem, even after an alcohol rub you still you don't have clean hands just dirty but sterile.
Big Brother is trying to pull the wool over our eyes.
