+The preceding four lemmas show that $(\R, \rho, \mu, 4)$ is a doubling metric measure space. Indeed, we even show
 that $(\R, \rho, \mu, 1)$ is a doubling metric measure space, but we may relax the estimate in Lemma \ref{real line doubling} to conclude that $(\R, \rho, \mu, 4)$
 is a doubling metric measure space.
