This is fine, but most of the people I know don't react in a normal way. What kind of benchmark is that?! I'm going to wind up writing 90k words on commonplace behaviour if I apply this tip! I'm going to chew this over now, at the gym. Again, another place where it's hard to find "normal' people. Trotting along for hours at a time on a machine in front of unforgiving mirrors is not a normal behaviour by any stretch of the imagination.
