Yesterday I needed to by some hamburger. I decided to go to the meat counter instead of buying the pre-packaged meat (which I assume didn't exist pre 1950?). Guess what? Human interaction. The nice guy behind the counter saw me, waved, gave me a universal signal that he would be right over to help, we exchanged friendly greetings, talked about the unusual weather. It was nice. Put a smile on both of our faces that may not have been there had I bought the prepackaged stuff.
I also found a Better Homes and Garden cookbook on Ebay that was published in 1949. I am going to get it because those recipes will be "safe"...i.e. contain ingredients that were accessible in 1949.
