The physical body is really the most perfect thing imaginable. An anatomist will always speak with the utmost admiration of the human heart, which functions in a wonderful way, even though human beings do little else throughout life than imbibe what is poison for it. Alcohol, tea, coffee and so on attack the heart in the most incredible fashion. But so wonderfully has this organ been built that it can withstand all this into ripe old age.
