The subject of age has ever been one which has attracted human thought. It leads us so near to the great mysteries that all thinkers have contemplated it, and many are the writers who from the literary point of view have presented us, sometimes with profound thought, often with beautiful images connected with the change from youth to old age. We need but to think of two books familiar more or less to us all, that ancient classic, Cicero's De Senectute, the great book on age, one might almost say, from the literary standpoint, and that of our own fellow-citizen, my former teacher and professor at the Medical School, Dr. Holmes, who in his delightful 'Autocrat' offers to us some of his charming speculations upon age.ABOUT THE AUTHORCharles Sedgwick Minot (1852-1914) was an American anatomist and embryologist known for his significant contributions to the fields of biology and medicine.
