Let me posit a theory I heard 30 years or more ago from an ancient old time Doctor I had a chance discussion with. He similarly maintained that the present “younger generation” 30 years ago were brainless in his view because starting in the mid-40’s TPTB started fortifying bread, milk, juice and pretty much everything with extra vitamins. Prior to that most males were 5’ something, and what happened is now we have most males getting to 6’ and over, with strong builds. He said the body keeps getting bigger and better, to the detriment of the development of the brain of its intellectual growth. Crackpot, or is there any element of truth here?
