[Do the math]

I'm an expert on the Spanish flu. Smoking was the main factor in the deathsbof the men who died. Every tissue sample from the men who died had elevated tobacco levels.

Interesting, but do have a source for this?

I would also caution against drawing this type of conclusion (correlation vs. causation) as one would have to know the rates of smoking in the general population at that time, also of those who recovered from the Spanish flu, how many of them were smokers vs. non-smokers, and also look at the flu deaths of women, were they also smokers or non-smokers?
