Medical Screening and Downton Abbey

Before watching Downton Abbey on Sunday, I had never heard of the feather girls. The scene was indeed striking - it made me fell quite uncomfortable.  Reading this piece in the telegraph reminded me of the anecdote on the most successful medical screening programme  - successful in terms of lives saved. During the first world war, all young men with a systolic murmur were not allowed to join up. This murmur, we now know is often 'harmless' and is compatible with full health. These healthy men were therefore saved from the horrors of the trenches.
