One of Life's Lessons

While preaching about forgiving ones enemies, the preacher asked for a show of hands of those who were willing to forgive their enemies. About half of the congregation raised their hands. The minister continued his lection and again asked for a show of hands. This time, 80 percent of his congregation raised their hands. Not giving up, the minister continued for fifteen more minutes. When he again asked for a show of hands, all members—except one—raised their hands."Mr. Jones,” asked the minster, “are you not willing to forgive your enemies?”"I don't have any.”Mr. Jones, that is very unusual. I know you are 86-years-old. Would you please come down to the front and explain to all of us how you have lived so long without making a single enemy in the world?”Mr. Jones teetered to the front and briefly explained, “Its easy. Ive outlived every one of them.”

Paul Sabatier

Born 5 Nov 1854; died 14 Aug 1941 at age 86. Organic chemist who shared the Nobel Prize for Chemistry in 1912 with Victor Grignard. Sabatier researched in catalytic organic synthesis, and discovered the use of finely divided nickel as a catalyst in hydrogenation (the addition of hydrogen to molecules of carbon compounds). The margarine, oil hydrogenation, and synthetic methanol industries grew out of this work. He found that increasing the surface area of catalysts such as copper and nickel by finely dividing them greatly increases their effectiveness. Sabatier did wide-ranging research of the use of catalysts in organic chemistry syntheses, revealing metals other than nickel, though less effective, can also behave as catalysts.
