Two guys, one 80 and one 87...

Two guys, one 80 and one 87, were sitting on their usual park bench one morning.
The 87 year old had just finished his morning jog and wasn't even short of breath.
The 80 year old was amazed at his friend's stamina and asked him what he did to have so much energy.
The 87 year old said, "Well, I eat Italian bread every day. It keeps your energy level high and you'll have great stamina with the ladies."
So, on the way home, 80 year old stops at the bakery. As he was looking around, the lady asked if he needed any help. He said "Do you have any Italian bread?"
She said, "Yes, there's a whole shelf of it. Would you like some?"
He said, "I want 5 loaves."
She said, "My goodness, 5 loaves ... by the time you get to the 5th loaf, it'll be hard."
He replied, "I can't believe it, everybody knows about this sh*t but me."

Francium

In 1930, the element Fr (francium) was discovered, the last naturally occurring element to be found. It is the heaviest alkali metal atom, with atomic number 87. Marguerite Pereyjoined (Oct 1929) the Institut du Radium in Paris in Oct 1929 as a technician for Marie Curie. Perey worked for years on actinium, which was anticpated to produce the new element by alpha decay. Finally, she was able to make thefirst entry about francium in her lab notebook on 7 Jan 1939, recording its half-life as about 20 minutes. A note in the Comptes Rendus was presented at the Académie des Sciences by Jean Perrin (9 Jan 1939). In his periodic table, Mendeleev anticipated its discovery, and provisionally named it eka-cesium. Perey gave it the name “francium.” She first used the symbol Fa, but changed it to Fr.«[Previously on this site as discovered 11 Jan 1930.]
