Why yes I am. Let's see, the air in a standard house is 74 degrees . The air from your mouth is 98.6 degrees. Hmmmm

I've seen electronic parts ( resistors, transistors, capacitors ) work or not work with a variance of 2-3 degrees.

Like I said, Know something about what you're talking about before you call it stupid.
