Now, what always astonished me was, that although the parlor might be crowded with ladies and gentlemen, all the windows were, as a rule, kept closed, with the result that the place was full of vitiated air.

Frequently after a short time I have had to slip away when I would willingly have remained longer to enjoy the charming company.

If I had done so, however, I should have taken into my lungs a large amount of the obnoxious atmosphere exhaled from hundreds of other persons in the room, to the injury of my health, and no one can give his fellows his best unless his health is hearty.

No wonder we often hear of a host or hostess being unwell after a big function.
Their feelings on the morning after are often the reverse of "good-will to men", and the cause is not a lowered moral heartiness but a weakened physical body through breathing too much air exhaled from other people's lungs.

When man understands, he will make "good health" a religious duty.
In connection with this I quote Dr.J.H.Kellogg, the eminent physician and Superintendent of the Battle Creek Sanitarium.
