Whenever someone tells me that glucose is the preferred fuel because we burn it first, I tell them that we burn alcohol before anything else. Using that logic, we should all be hocked up on liquor 24/7 . What makes real sense though, is that the body will metabolize the most toxic fuels first.
Some tips on electronics in cold: 1  Most electronic components are not damaged by ânormalâ cold temperatures. 2  Condensation can be a problem, if the temperature cycles between warm and cold with humidity.  Batteries lose capacity in cold (battery powered devices might not work in the cold)
Condensation becomes a very real problem at high humidity. Very low humidity, on the other hand, can cause the components of a device to become brittle. Electronics are usually designed for operation in normally-experienced humidity ranges, and so will operate correctly in the healthy human range of 30 to 50 percent.
