Also, we are warm blooded so heat generation is constant like a treadmill. In order to prevent heat buildup and feel comfortable, the heat has to transfer from the body to the environment which requires a temperature difference, which is why 98.6F ambient temperature feels hot to us, but 72F feels comfortable because the air conducts away heat at a balanced rate of exchange. As you mentioned air is an insulator so heat conduction is slower than with solids such as metal or plastic. Exposed to open air the skin's surface temperature drops a little but does not reach ambient temperature because of body's continual heat generation. A head band with plastic or metal contacts would conduct away more heat so the skin's surface temperature will drop further, which is why solids feel colder to the touch.</p></div>

No. We're already in the Matrix. What we're talking about here is a Matrix inside a Matrix. Its kind of a neat concept, and kind of meshes with the whole idea of the age old "tree of life" concept, where this ephemeral god concept is the head node, which branches to child archangel nodes, which then branch to angels, which all fan-in to a single child "heaven" object, or love-area. Some of the angels "fell", meaning their head nodes became the heaven object, and instead of this interesting god-angels-heaven circle, the branching continued, ultimately leading to the creation of this universe.
<br> <br>
I would point out that we as consciousness-seeking race are busy playing god, and creating universes, such as can be found in games, puzzles, stories, religion, books, mathematics, science. And those developed in precisely that order. Games is to god, as puzzles are angels, as stories are to people, as religion is to angels, as mathematics and science are to god. Its all one big recursive refinement loop.</p></div>

The human body is only slightly hotter than the room its in,
say 38 Celius versus 20. That leads to a tiny Carnot efficenty
which is the best physics allows, then you need to factor
in that thermocouples and thermoelectric generators are only
a few percent efficient, so you end up with a tiny ammount
