That was my thought...

When I was home for a weekend from Camp Pendleton in 1967 I started having terrible chestpains....went to the ER and some rookie diagnosed this 20 year old as having had a heart attack.

That got squared away overnight, and correctly called pleurisy; I'd had "mess duty" for the previous couple of weeks - in the scullery/dishwashing area - and it was assumed that the extremely hot and steamy environment caused it all.
