When you're drinking a hot beverage, you want that beverage to remain hot. Of course you do! You're a human being with needs. Sadly, it won't - you can't fight the second law of thermodynamics; even if you prime your cup first, eventually entropy will have its way. Eventually, you'll take a swig of your coffee or your tea and get a mouthful of lukewarm disappointment. If your 9am cup tastes like a brand new day, full of promise, then your 10:15 dregs remind you that it's seven hours until you can start drinking.
