Mainline your caffeine, it’s the only way to be sure.
I saw a bit recently on a youtube video about how humanity lived on beer and wine forever because water was often tainted with bacteria (the alcohol killed it). Even babies were fed wine and beer.
And then coffee and tea (the boiling water killing bacteria) were discovered and human productivity exploded.
Factual? Who knows?
But it sure "sounds" good.
Mmmmmm. Coffee.
