I am rather proud of myself for reading and making sense of this book, since my education in genetics (besides watching my children develop) ended in ninth grade.  Watson's account is really quite charming and does not go far beyond that ninth grade biology lesson, which is to say that it was also mindblowing to think about how much it took to get to a discovery that now all high schoolers learn in the most basic of science classes.  I also enjoyed the reviews at the end more than I thought they would -- they added a good amount of context and were highly amusing.
