'Thousands dying because hospitals are understaffed.'

A Telegraph headline.
But how can this be true?
Last year, I was in hospital for a whole extra day after being released just waiting for one blood test and to be given a few pills.
Does that sound as if there is a crisis?
Sorry? - What did you say? - Inefficiency? Ah, well.
Extrapolate from my situation and ask how many people are 'bed-blocking' for no good reason whatsoever across the entire UK on any single day!
