While on a road trip, an elder...

While on a road trip, an elderly couple stopped at a roadside restaurant for lunch. After finishing their meal, they left the restaurant and resumed their trip. When leaving, the elderly woman unknowingly left her glasses on the table. And, she didn't miss them until after they had been driving about twenty minutes. By then, to add to the aggravation, they had to travel quite a distance before they could find a place to turn around in order to return to the restaurant to retrieve her glasses.
All the way back, the elderly husband became the classic grouchy old man. He fussed and complained and scolded his wife relentlessly during the entire return drive. The more he chided her, the more agitated he became. He just wouldn't let up one minute.
To her relief, they finally arrived at the restaurant. And as the woman got out of the car and hurried inside to retrieve her glasses, the old geezer yelled to her, "While you're in there, you might as well get my hat".

Cocaine anaesthetic

In 1884, cocaine was first used as a local anaesthetic to immobilize a patient's eye for eye surgery by Carl Koller. His success initiated the modern era of local anesthesia, with cocaine also quickly adopted for nose and throat surgery and for dentistry. For Koller, a Czech-born American ophthalmologist, the clue for this use was when he noticed that cocaine had a numbing effect on the tongue. He made many experiments on animals before introducing its use on humans. Cocaine was isolated in 1859 and was synthesized in 1885. It was later found with high doses or repeated use, it caused erosion of the corneal epithelium in high doses and it was replaced by less toxic, synthetic local anesthetics such as tetracaine and proparacaine.«
