Don't have to.

I start my cup when I go out to feed the chickens and the dickie birds. When I come back in it's the right temperature most times.

I hate coffee so hot it burns the tongue. In the past have made ice cubes out of coffee for when I was in hurry to drink it. Didn't lessen the strength that way.

The desert is a true treasure for him who seeks refuge from men and the evil of men.
In it is contentment
In it is death and all you seek
(Quoted from "The Bleeding of the Stone" Ibrahim Al-Koni)
