Three old men were sitting around talking about who had the worst health problems. The seventy-year-old said, "Have I got a problem. Every morning I get up at 7:30 and have to take a piss, but I have to stand at the toilet for an hour 'cause my pee barely trickles out."
"Heck, that's nothing, " said the eighty year old. "Every morning at 8:30 I have to take a shit, but I have to sit on the can for hours because of my constipation. It's terrible".
The ninety-year-old said, "You guys think you have problems! Every morning at 7:30 I piss like a racehorse, and at 8:30 I shit like a pig. The trouble with me is, I don't wake up till eleven."

First genetically engineered vaccine

In 1981, the first genetically engineered vaccine was announced: the first effective subunit vaccine for any animal or human disease using gene splicing. It was designed to prevent hoof and mouth disease (FMD). The work was done by the U.S. Dept of Agriculture scientists who by 1975 had discovered that injection of VP3 (a protein derived from a portion of the coating of FMD virus) confers immunity to the disease. In 1980, the USDA team turned to recombinant DNA technology, and collaborated with scientists from Genentech, a private company. They inserted a bioengineered plasmid containing the gene for VP3 into Escherichia coli bacteria which grew obeying orders from the guest DNA, mass-producing the VP3 proteins for the vaccine.
