😳 *WHY?* ❓❓
*Why do our ears ‘pop’ in an aeroplane or on a steep hill road?*
Our middle ear, the air-filled space behind the eardrum, is connected to the back of the throat by a narrow passage called the Eustachian tube, which normally stays closed. When we climb or descend quickly — in an aeroplane, a lift or on a ghat road — the air pressure outside changes faster than the pressure inside the middle ear, so the eardrum is pushed inwards or outwards, making the ear feel blocked. When we swallow, yawn or chew, the tube opens briefly and air rushes in or out to balance the pressure, and the eardrum springs back with a small ‘pop’. That is why chewing gum or sucking a sweet helps during take-off and landing, and why a cold, which can block the tube, makes flying uncomfortable.

14 November — Important Days
Children’s Day (Bal Diwas): Celebrated in India every year on 14 November, the birth anniversary of the first Prime Minister, Jawaharlal Nehru, who was fondly called ‘Chacha Nehru’ for his love for children. After his death in 1964, his birthday came to be observed as Children’s Day. Schools hold cultural programmes, and the day highlights children’s rights, education and well-being.
* World Diabetes Day
Observed on 14 November, the birthday of Sir Frederick Banting, who co-discovered insulin with Charles Best in 1921. It was started in 1991 by the International Diabetes Federation (IDF) and the World Health Organization (WHO) in response to the rising number of diabetes cases, and became an official United Nations day in 2006. It is marked by a blue circle, the global symbol of diabetes awareness.

🐣💐 *BORN TODAY*
*Sir Frederick Banting* (born 14 November 1891)
Frederick Grant Banting was born at Alliston in Ontario, Canada. A surgeon and medical scientist, he worked with Charles Best at the University of Toronto in 1921 to isolate insulin, the hormone that controls blood sugar, and in January 1922 it was first used to treat a 14-year-old diabetic boy, Leonard Thompson. In 1923, Banting and John Macleod received the Nobel Prize in Physiology or Medicine; at 32, Banting remains among the youngest winners of the medicine prize, and he shared his prize money with Best. Insulin has since saved millions of lives. He died in an air crash in Newfoundland in 1941.
