On log scale the line plotted on O2used/gm body mass depending on total
body mass of organism is a straight line starting from top left and going
down to bottom right.  In a non-log scale, the line is almost asymptotic
and hugs the total body mass axis after about horse size.  Size does
matter--but after a certain threshhold is reached there is neglible
benefit (this, anyway, is how I try to convince my sig. other--she
says: when you reach horse-size, we'll start talking).
