People are similar to bacteria in one sense, i.e. there are always a few in any population who are naturally immune to certain things, therefore they don’t really “evolve”. It is just the naturally disease resistant people who propagate.
So... we are the result of our environment.
I disagree with this thesis.
Most communicable diseases to which humans are susceptable are contracted from domesticated animals. Hence areas of the world where domesticated animals weren’t the norm before the arrival of Europeans, such as the Western Hemisphere, were horrifically affected by diseases like small pox, which originated from close contact with cattle.
Cities may benefit the immune system but they make people crazy. I’d rather just wade through a septic tank once a month.
A visit to Cap Hatian would cure them of this notion.
There might be a lot of truth to this study. I’ve watched city workers and their immune systems seem pretty strongly resistant against work or speed.

It's amazing how little Pakistan has progressed since then. What modernity they have has trickled in from elsewhere.
