Now, I'm as OCD as the next man, but even by my standards, the NHS hand-washing instructions below seem a tad OTT. I'm like HOW many stages?
We're told at the end that the whole process should last 15-30 seconds. That's quite a spectrum. They're saying you can wash your hands for half the length of time that someone else does and yet still fall into the 'clean' category. So why would anyone go for 30 seconds? You'd just cheat and do 15, wouldn't 't you?
