That is true if you can still hear sounds like the balls in our bearings
clicking together. Those of us who are acoustically challenged will have
to ask a younger friend to listen to the balls clicking together. A couple
of years ago I was running a marathon while wearing a heart monitor. I had
set an alarm to warn me when my heart rate exceeded 155 beats per minute.
The problem was that I couldn't hear the alarm. My fellow marathoners kept
telling me that my heart rate alarm was sounding. It was disconcerting to
have a guy/gal running next to me say, "Your heart monitor is telling you
to slow down." <br>

Sorry about straying from the subject.<br>
