Many sections of this book were eye-opening and they helped to change my perception of certain events. I particularly liked the thought that women who carry items on their head have better posture and bone density than those that don’t:

The tradition has been to think that aging causes bone weakness (bones lose density, become more brittle), as if there was a one-way relationship possibly brought about by hormones (females start experiencing osteporosis after menopause). It turns out, as shown by Karsenty and others who have since embarked on the line of research, that the reverse is also largely true: loss of bone density also causes aging, diabetes, and, for males, loss of fertility and sexual function.

Some of the ideas, especially the thought that small wars are good for the population as a whole, are controversial, but I found them thought provoking and enjoyed the little arguments they created in my head!
