Grandpa, Did God Make You?

A little girl was sitting on her grandfather’s lap as he read her a bedtime story. From time to time, she would take her eyes off the book and reach up to touch his wrinkled cheek. She was alternately stroking her own cheek, then his again. Finally she spoke up, “Grandpa, did God make you?”“Yes, sweetheart,” he answered. “God made me a long time ago.”“Oh,” she paused. “Grandpa, did God make me too?”“Yes, indeed, honey,” he said. “God made you just a little while ago.”Feeling their respective faces again, the little girl observed, “God’s getting better at it, isn’t He?”

John Elliotson

Died 29 Jul 1868 at age 76 (born 29 Oct 1791).English physician who advocated the use of hypnosis in therapy and who in 1849 founded a mesmeric hospital. He was one of the first teachers in London to emphasize clinical lecturing and was one of the earliest of British physicians to urge use of the stethoscope, together with the methods of examining the heart and lungs which are used to this day. In 1823 acupuncture was mentioned in the first edition of the Lancet and in 1824 Dr. Elliotson began to use this method of treatment. In 1827 he published a series of results on the treatment of forty-two cases of rheumatism by acupuncture. In 1834 he became physician to the University College Hospital, where his interest in hypnosis led to conflicts with the hospital's medical committee and his resignation in 1838.
