I rode my wheel more, chiefly because it was permanently out of pawn; and I boxed and fenced, walked on my hands, jumped high and broad, put the shot and tossed the caber, and went swimming.

And I learned that more sleep is required for physical exercise than for mental exercise.

There were tired nights, bodily, when I slept six hours; and on occasion of very severe exercise I actually slept seven hours.

But such sleep orgies were not frequent.
There was so much to learn, so much to be done, that I felt wicked when I slept seven hours.

And I blessed the man who invented alarm clocks.
And still no desire to drink.
