A highlight of this book was that it really was quite interesting. A lot of the physiological traits mentioned could affect personality very logically, and I liked that. For example, the rigidity of osseous type due to large bones makes sense to me because bones are rigid. On the other hand, most of the theories mentioned in the book were laid out only in a logical way instead of being backed by research. This bothered me because, though many of these things seem to be observations, the observations/experiments were not cited. Thus, I don't know that there were legitimate experiments involved or if the author only watched a few people for an hour.
Something else I found interesting was the effect of food on personality due to body type. On page 10 the author states, “Recall [an] occasion when a square meal made a decided difference in your disposition within the space of thirty minutes. If one meal has the power to alter so completely our personalities temporarily, is it any wonder that constant overfeeding causes everyone to love a fat man?” On the other end of the spectrum, “The brain worker long ago discovered that a heavy midday meal gave him a heavy brain for hours afterwards" (Page 58). From these two quotes we see that, on all sides, eating habits greatly impact personality, which I thought was a very interesting correlation. On the whole, I actually did enjoy this book.
