A husband is advised by a psyc...

A husband is advised by a psychiatrist to assert himself. "You don't have to let your wife henpeck you! Go home and show her you are the boss!"

Of course, the husband takes the doctor's advice. He rushes home, slams the door, shakes his fist in his wife's face, and growls, "From now on, you're taking orders from me! I want my supper right now and when you get it on the table, go upstairs and lay out my best clothes. Tonight, I'm going out with the boys and you are going to stay at home where you belong! And another thing... guess who's going to comb my hair, give me a shave, and tie my necktie?"

His redheaded wife says calmly, "The undertaker."

Dr. Thomas Beddoes

Died 24 Dec 1808 at age 48 (born 13 Apr 1760). English physician and philosopher who, in the late 1780s, began to explore the potential medical uses of gases. He founded the Pneumatic Medical Institute in Bristol (1798). The institute offered oxygen therapy, but because Beddoes' assumption–that some diseases would naturally respond to a higher or lower oxygen concentration–was incorrect, the treatments offered no real clinical benefit. However, Humphry Davy, launched his chemistry career there, researching nitrous oxide (“diminished nitrous air”). Beddoes published Hygeia: Or Essays Moral and Medical, on the Causes Affecting the Personal State of the Middling and Affluent Classes, 3 vols. (1802), a formal regimen for daily diet, exercise, and sleep for illness prevention.
