Since the physiology workbook, I’ve been hooked on these things. I found this one used in Singapore, and got an extra discount because someone had already colored the cell membrane on page 30. Happy day!

I started this book while working at a summer camp in Russia, just before leaving for massage school. I was hoping to get a jump start on my studies, but (go figure) I really couldn’t focus on anything living in a cabin with 35 kids.
Most people in Russia go to the forest to collect mushrooms, have a bbq or whatever, but I snuck in there with my pencils and workbook, found a stump to sit on, and colored away a couple hours when I could.
Those were by far the most peaceful and enjoyable moments of that summer. Oh, and I learned some physiology too.
