I’d like to see a map like that for 100 years ago. Looks to me like basic food and sanitation can extend lives anywhere and everywhere.
sanitation is the #1 thing in reducing sicknesses in people. so many xmission vectors are rendered to very small percentages. otherwise they are huge problems b/c they not only transmit, their numbers explode due to the sanitation problem they live off of. becomes epidemic/pandemic.

Here in Texas I once attended a class lecture on health issues and the instructor asked the class what they thought was the leading cause of death back in the 19th century. I immediately raised my hand.
Instructor: “Yes, you in the back, what do you think?”
Me: “Indians”
The class was in an uproar for the next five minutes.
