Floods kill, long after the water has gone

In New Orleans they called it the "Katrina cough".

People would just get sick from random things and die 6 months or a year after they'd survived the hurricane. Happened to one relative on my father's side of the family. He just never shook the cough, right up until the day he died.

I will say that while I was in my 30s at the time, I took advantage of the architectural salvage goldmine that was New Orleans after Katrina. You could get priceless lumber, flooring, etc from salvaged 18th and 19th century houses that got flooded, which was great... until you didn't wear enough protective equipment while cleaning them up, and then you also got the cough.

The difference in 35 and 75 is the old uncle on my father's side of the family died from it, while I just suffered the worst sinus infection I ever had, and was fine after a few weeks.
