What is unusual about the following paragraph?

It looks so ordinary you’d think nothing was wrong with it at all – and, in fact, nothing is. But it is unusual. Why? Study it, think about it, and you may find out. But you must do it without coaching: I’m not going to assist you in any way. No doubt, if you work at is a bit, it will dawn on you. Who knows until you try? So hop to it, try your skill and pray for luck. Par is about half an hour.

A medical researcher with the National Institute of
Health observed that a neurologically based chemical
reaction in the body takes 80 minutes when he wears
a wool jacket, but when he isn’t wearing the
wool jacket, the same reaction always takes a full hour
and 20 minutes. Can you explain why this might be so?

Answer:

The chemical reaction takes the same amount of time.
Eighty (80) minutes equals 1 hour (60 minutes) and
20 minutes.
