Picked up a book at the antique malls.. Eugenics by Herman Rubin.
It tells about some really interesting stuff such as "why men are really attracted to blondes" "The origin of kissing" "Nervous women" "Medicine of the future" "choosing the sex of your baby" "How water can cure" "How to stop snoring" "Headache causes and preventions" "How long you will live" and other stuff such as modern day in the bible
and many other very interesting things.. this book was written in 1933... and is more informative than many other textbooks i've read... Give it a look, its available online as well.
