&gt; Sirens, rooftop fans, construction and upstairs neighbors who clomp about like a team of clog-dancing Clydesdales are common conditions of city living.<p>It&#x27;s amazing how oblivious some people are to the fact that every step they take is actually a huge stomp. I&#x27;m surprised their ankles don&#x27;t shatter from repeatedly hammering their full body weight down onto their heels.<p>Isn&#x27;t it uncomfortable for them to use their heels like pistons? How does it not hurt?
