10/36 In fact, it is pretty safe to say that, if somebody doesn't feel a draft the room is not being properly ventilated. At one time this was considered a very serious drawback--drafts were supposed to be so dangerous. But now we know that a draft is only air in motion, and that air in motion is the _only air that is sure to be pure_. There is nothing to be afraid of in a draft which is not too strong, if you are clean outside and in, and reasonably vigorous. If the draft is too strong, move away from the window or the door. |
