2/n Heart rate is in fact *on average* in Z2, but with a STD of .092. Roads have hills so it is ludicrous to aim at constant HR. [Note flaws in "research" on Z2]. You get the same results living in hilly terrain (Mediterranean); in Sardinia centenarians climb hills like goats. https://t.co/qr0pHyNIBF — PolitiTweet.org
