Some Improvements in Hell

An engineer died and ended up in Hell. Soon, he became dissatisfied with the level of comfort in Hell, and began designing and building improvements. After a while, they had flush toilets, air conditioning, escalators. The engineer was a pretty popular guy.One day God called to Satan and said with a sneer, "So, how's it going down there in Hell?" Satan replied, "Hey, things are great. We've got air conditioning and flush toilets and escalators, and there's no telling what this engineer is going to come up with next."God exclaimed, "What? You've got an engineer? That's a mistake--he should never have gotten down there in the first place. Send him back up here.""No way," replied Satan. "I like having an engineer on the staff, and I'm keeping him."God threatened, "Send him back up here now or I'll sue!"Satan laughed and answered, "Yeah, right. And just where are YOU going to get a lawyer?"

David Marine

Died 6 Nov 1976 at age 88 (born 20 Sep 1888). American pathologist whose substantial research on the treatment of goitre with iodine led to the iodizing of table salt. During 1917-22 he ran a trial on a large group of schoolgirls to show that an iodine supplement dramatically reduced the incident of goitre (a major swelling of the thyroid gland in the neck). His results clearly showed the important of iodine in the diet. Dr. David. M. Cowie promoted the production of iodized table salt, first sold on 1 May 1924, and later throughout the U.S., greatly reducing the incidence of goitre. Marine worked on salt iodization for the World Health Organization, further spreading its benefits. (As early as 1821 French chemist Jean-Baptiste Boussingault had observed that iodine-rich salt could treat goiter.)«
