Whenever I take stock of various data such as the number, mass, distance, radius, speed, surface temperature, age, brightness, metallicity, etc. of various celestial bodies, a natural sense of greed and abundance, like a child entering an empty and unattended candy store, arises. Halley lived to be 85 years old, Willliam Herschel lived to be 83 years old, and his sister Caroline lived to be 97 years old. Dealing with astronomical numbers regularly contributes to longevity, which is no exaggeration!
