"You mean he's not out of the woods yet, Doctor?" the lad asked.
"Not by a long shot," was the reply. "You can't play any monkey-shines with the heart. Judging by the shape that fellow's heart is in, I should be inclined to say he's been smoking for nearly ten years, smoking pretty heavily, too. And he can't be a day over twenty-three!"
"Do you suppose that had anything to do with his drowning?"
"Of course it had," the doctor answered. "Swimming is a real athletic exercise and you've got to keep in shape to swim well. What's more, you've got to have a decent heart to start with. But if a youngster piles into cigarettes, it's a safe bet that he's going to cripple himself for athletics in manhood."
"But you smoke, Doctor!"
"Sure I do," the other rejoined. "And I swim, pretty nearly as well as any of you young fellows. But I didn't start any cigarette business when I was a kid, the way lots of boys do now. It wasn't until I was in college that I smoked my first pipe."
"Then you think it's all right for a chap to smoke after he's grown up?"
"I wouldn't go as far as to say that," the doctor said, "but there's no doubt that the cases which have turned out worst are those in which the habit began early. Nature's a wise old scout, Eric, and you're apt to find that a man who's likely to be hurt by smoking won't develop a craving for it unless he started too young, or unless he forced himself to excess."
The boy wanted to question the doctor further, for he was thoroughly interested in finding out that smoking prevents an athletic manhood, when the speaker was interrupted by a cry from the half-conscious man.
"Jake!" he called.
