Actually if you have such vast experience in the world of varanids you would know how terribly hard it is to find good keepers. They are nothing like the snake community where every newbie with a menards rack can start a breeding facility. I am far from an elitist and am very interested in the gurus you claim to know, if you would like I will PM you and ask you so you do not have to put all their names out here. I find though I gain more knowledge from croc keepers and monitor keepers than the cash crop keepers (
BP, boas, leoapard geckos, BD and all the other caresheet cults out there).
Now yes reptiles don't sweat but you would be fool to think they can not retreat to a cool part of the enclosure. Reptiles are fully aware of their CTM and their PBT, this goes back to the "boil a frog" statement which is false.
