I will grant you three wishes . . . maybe!?
An older couple were walking on a beach when the husband tripped over a bottle and a genie came out.
“You can each have one wish,” said the genie. The wife made her wish first “I would like to travel around the world, with my husband,”.
Suddenly there appeared in her hand two tickets for travel around the world.
Now it was the husbands turn, “Well” said the husband, with a naughty look on his face “I wish I can have a younger companion,” . The words were barely out of his mouth when poof,
he aged 20 years!

Edward FarberBorn 22 Jul 1914; died 22 Jan 1982 at age 67.Edward Rolke Farber was an American inventor who devised a portable, battery-operated stroboscopic flash unit for still cameras (1937) that effectively “stopped action.”He began his career as a photojournalist on the staff of the Milwaukee Journal. After studying electrical engineering at Northwestern University, Farber went on to design flash equipment for the U.S. Army during World War II, and then established his own electronic-flash manufacturing firm. He was a good friend and collaborator of Harold Edgerton and developed the first practical portable strobe flash for news photographers. In 1942, the Milwaukee Journal became the first newspaper to furnish all of its photographers with the portable flash. Weighing only 13.5 pounds, it was a considerable improvement over the 90-pound units photographers used prior to Farber's invention. He sold his Strobe Research firm in 1954. He was a photographic adviser to the U.S. Government during its intercontinental ballistic missile testing program in the late 1950's. |
