A little boy was sitting outside a store eating one snickers candy bar after another, when an older man walked up and said: "You shouldn't be eating so much candy, it'll rot your teeth, it's just bad for you to eat so much candy."
The little boy looked up and said: "My grandfather lived to be 95 years old."
The older man asked: "Oh? by eating snickers candy bars?"
The little boy said: "No... by minding his own business."

Nasir ad-Din al-Tusi

Died 26 Jun 1274 at age 73 (born 18 Feb 1201).Muhammad ibn Muhammad ibn al-Hasan al-Tusi was a Persian philosopher, scientist, mathematician and astronomer who made outstanding contributions in his era. When The Mongol invasion, started by Genghis Khan, reached him in 1256, he escaped likely death by joining the victorious Mongols as a scientific advisor. He used an observatory built at Maragheh (finished 1262), assisted by Chinese astronomers. It had various instruments such as a 4 metre wall quadrant made from copper and an azimuth quadrant which was Tusi's own invention. Using accurately plotted planetary movements, he modified Ptolemy's model of the planetary system based on mechanical principles. The observatory and its library became a centre for a wide range of work in science, mathematics and philosophy. He was known by the title Tusi from his place of birth (Tus).
