Actually you&#x27;re not sure you could do that. When do people ever stand perfectly still for hours on end? We get the difference between anecdotes and data, but it&#x27;s also ok to formulate testable hypotheses in here.<p>Anyway this is like saying &quot;Buying a bike won&#x27;t make you thin&quot;. Yes, you have to ride the bike. But the availability of a bike in your house greatly raises the chance that you&#x27;ll ride on any given day. It&#x27;s indirect, but still a pretty good idea.
