CHAPTER XIX.
LAUGH AND LIVE Again I find it expedient to resort to the personal pronoun and therefore this final chapter is to be devoted to "_you_ and _me_." There are facts you may want to know _for sure_ and one of them is whether or not I live up to my own prescription.
I do--_and it's easy_! I have kept myself happy and well through keeping my physical department in first class order.

If that had been left to take care of itself I would surely have fallen by the wayside in other departments.

Once we sit down in security the world seems to _hand us things we do not need_.
Fresh air is my intoxicant--and it keeps me in high spirits.

My system doesn't crave artificial stimulation because _my daily exercise_ quickens the blood sufficiently.

Then, too, I manage to _keep busy_.
That's the real elixir--_activity_! Not always physical activity, either, for I must read good books in order to exercise my mind in other channels than just my daily routine--and add to my store of knowledge as well.
Then there is my _inner-self_ which must have attention now and then.
For this a little solitude is helpful.
