I know I shouldn't, but...

If you start with, say, 140 degree water, and want to go to 32 degrees,
then how are you going to get there without going through every lower
temperature in between?  And if it takes a certain time to get from 
140 degrees to that lower temperature(say, 45 degrees), how is it going to
take less time to go to 45 degrees and then to 32 degrees than to start at
45 degrees?  A similar situation exists with the boiling issue.  It is very
true that the initial heat gain or loss is much faster with the greater
difference in temperature, but once you've gotten to the other starting
point, you've got exactly the same distance to go that you had from there.
My mathematical skills are not what they should be, but I don't believe that
you can prove that X plus Y is ever LESS than X, given that X and Y are
both positive.  Nor can you show that the distance from one point to another
changes as a result of whether you start from there or are just passing through.

I used to run a car wash.  Now the folk around there were not the great erudite
sort that we are communicating with here, but when they came up with that line,
and I explained it to them, they eventually listened.  Is it possible that there
are some things so obvious that the more intelligent just can't see them?
