A man asked his doctor if he thought he'd live to be a hundred. The doctor asked the man, "Do you smoke or drink?"
"No," he replied, "I've never done either."
"Do you gamble, drive fast cars, and fool around with women?" inquired the doctor.
"No, I've never done any of those things either."
"Well then," said the doctor, "what do you want to live to be a hundred for?"

Hydrogen balloon

In 1783, the first experimental hydrogen-filled balloon left the Champs de Mars, Paris, unmanned, and reached 900-m altitude. Under the auspices of the French Academy of Sciences, Jacques A.C. Charles sent up a 13-ft (4-m) diameter hydrogen- filled balloon of rubber- coated silk. One of the spectators was the American ambassador to France, Benjamin Franklin. The gas had been manufactured, beginning on 23 Aug 1783, by pouring 225-kg of sulphuric acid over half a ton of scrap-iron. Able to lift about 9-kg, it traveled 24-km in about 45 minutes. The balloon descended close to the little village of Gonesse, where frightened local farmers attacked it with pick axes and spades, leaving only torn remains.
