We smile as we go about doing it.
A friend once said to a banker: "How do you know when to lend money ?" The banker replied: "I look a man in the eye and then _I do or I don't_." The friend said: "I would like to borrow ten thousand dollars--now!" "You shall have it, Sir," the banker replied.
This meant that the man who asked for the loan was in a state of physical and mental preparedness.

If he had gone into the banker's office looking like an animated tombstone he wouldn't have had much of a chance to borrow the ten thousand.

It goes without saying that the open-faced, hearty fellow inspires confidence.

There is nothing coming to the dried-up, sour chap, and that's what he usually gets.

And what we get is largely a matter of our physical well being.
