If the tea bush were a Christmas tree, pickers would only take leaves from the bough where the star is placed, the very tip, and perhaps a few of the branches with ornaments on them.  Sarah Rose “For all the tea in China: Espionage, empire and the secret formula for the world’s favourite drink”

Tea is an addiction, but an addiction different from all others. It is milder, a habit relatively easily broken. It is more universal. Most unusually, it is good for the addict. And it is largely unnoticed both to those addicted and others. Indeed, the conquest of the world by tea has been so successfull that we have forgotten that it has happened at all. Tea has become like water or air, something that many of us take for granted. Alan Macfarlane, “The empire of tea”

Habitual tea drinkers begin to feel restless if they do not get their cup at the usual time. In my opinion, the usefulness of tea, if any, consists in the fact that it supplies a warm sweet drink which contains some milk. The same purpose may well be served by taking boiled hot water mixed with a little milk and sugar. Mahatma Gandhi in “A Key to Health”
