Review: interesting notebook - interesting neat, tidy, sleek notebook to put interesting notes in. Looks just like advertisement photo. :) can't wait to fill it up with bits of coles notes from my new quantum biology books. Perfect. First interesting fact being added to my notebook: you are not 'a' body but a cluster of 50 trillion independent single celled life forms that formed a community that you perceive as your body! Neat journal for a cool topic I study as a hobby.
