City life is built around noise/hustle. There is a reason coffee is a stereotype in New York City. This routine is emphasized over the needed eight hours of sleep.

Water quality via plumbing and even rain quality is generally lesser in cities. Rain is often affected by air pollutants that come from buildings and vehicles which mix with cloud matter, while plumbing quality is affected by the quality of pipes and aquatic infrastructure which is typically further from the source.

Walking is affected because you're living your life in an urban jungle with varying levels of danger (depending on the city) where your main range is measured in blocks rather than the openness of the world around you.

Have people in this industrial-loving place thought the advice was simply some kind of jab and chose to think rashly about it?
