Have you tried putting it in the 'fridge? WFL
Too high tech!
For someone who hates drinks being very hot, likes coffee, is impatient, and doesn't want ice cubes (too much hassle, alters taste), I dug up an aluminium rod, about 15 mm in diameter and 15 cm in length. You only need to dip that into the drink _shortly_ to get the temperature you want.
Cue happy pal.
