This is a misleading title because all the article states is to take the stairs, pushing five flights which is not an everyday activity. The title implies that any exercise even without sweating is beneficial for the heart, but in realty, exercise does not have to involve the gym, and that could be considered simple, but sweat investment is the most beneficial. "Beloved, I wish above all things that thou mayest prosper and be in health, even as thy soul prospereth" (3 John 1:2).
