Here is a related question for you:  After you take your teabag out, you
hear the phone ring.  You know you may be gone for a while and you want
your tea to remain as hot as possible.  You always add N ounces of cold
milk to your tea before drinking it.  In order to maximize the
temperature of the tea in T minutes from now should you add the milk now
or wait until you come back and are about to drink the tea?
