Difficult part:

I'm a little confused by the factoring done in the Vblood equation at the bottom of page 33, but other than that, I think I generally understood the math.

Reflective part:

On the one hand, the way much of life seems to obey simple scaling laws for metabolism and similar factors is impressive; on the other hand, the controversy around much of this, as well as some of the initial, incorrect suppositions of a 2/3 scaling factor shows that math cannot make predictions in a vacuum, even if the predictions are convenient.
