I keep reading health books on how to cheat death! Current book I'm taking in will likely not be all that helpful though. It is in part about how the 1918 Spanish influenza was not caused by a virus. Instead there are other possible causes such as over doses with aspirin, and being exposed to the deadly chemical warfare gas phosgene. The author is trying to make the argument that phosgene gas could have been in part responsible for the Spanish influenza. He does a good job. Apparently the two had identical symptoms that doctors at the time were not able to tell apparent, phosgene poisoning and the Spanish flu. 100 million dead from the Spanish flu. Rather grim statistic.
