NPI's, non pharmaceutical interventions? That's all they had in 1918 for crying out loud. The only pharmaceutical items were leeches and laxatives. Secondly, shutting down restaurants and bars, gyms, hair salons, and other business couldn't possibly have any effect on the economy. I hope our tax dollars didn't pay for this ridiculous study. I swear the people who publish this tripe really think we are all stupid.
