My boyfriend lent me this book and said it's weirdly fascinating, so I took it with me when I had to sit all day at a track meet. I actually ended up thoroughly enjoying it. It's a bit dated in places, obviously, being published in 1979, but the research and research notes are fascinating and I enjoyed the pictures quite a bit. I wonder how a more current study of these same gestures would differ, given our cultural shifts since then? This was a super fun read.
