### The Ring

An older, white haired man walked into a jewelry store one Friday evening with a beautiful young gal at his side.
He told the jeweler he was looking for a special ring for his girlfriend.
The jeweler looked through his stock and brought out a \$5,000 ring and showed it to him.
The old man said, "I don't think you understand, I want something very special."
At that Statement, the jeweler went to his special stock and brought another ring over.
"Here's a stunning ring at only \$40,000," the jeweler said. The young lady's eyes sparkled and her whole body trembled with excitement.
The old man seeing this said, "We'll take it."
The jeweler asked how payment would be made and the old man stated, by check. "I know you need to make sure my check is good, so I'll write it now and you can call the bank Monday to verify the funds and I'll pick the ring up Monday afternoon," he said.
Monday morning, a very teed-off jeweler phoned the old man. "There's no money in that account."
"I know," said the old man, "but can you imagine the weekend I had?"
Don't mess with Old People.

### Dolly death

In 2003, Dolly, the world-famous firstcloned sheep, was put down, at age about 6½years. She had been suffering from a progressive lung disease. Dolly, a Finn Dorset sheep, wasborn at the Roslin Institute, Edinburgh, Scotland on 5 Jul 1996. This accomplishment, the first mammal cloned from an adult cell was announced on 23 Feb 1997. Using microscopic needles, scientists had replaced the nucleus of an egg cell with the nucleus from a parent cell (an udder cell, in Dolly's case). The resulting embryo was implanted into the womb of a third, surrogate sheep. Somehow, the egg cell reprogrammed the donated DNA contained within its new nucleus. Normal life expectancy of a Finn Dorset sheep is about 11 to 12 years. Dolly's early death, like her birth, raised new controversy about the wisdom of cloning.«
