In psychology and philosophy there is an ongoing question whether brain and mind are perhaps the same thing. I can tell you they are not.
The brain is a low power transmitting mechanism made from beef-patties which operates on a frequency band from 0 to 25 Hz at very low power, not subject to FCC rules which don't kick in until 9 kHz on up.
The mind is the intelligent modulation of information carried on a brain's carrier. Speech and the written word, two auxiliary outputs of brain, allow mental thoughts to be translated for other people to hear or read.
Part 15 radio broadcasting depends on thinking brains to manage and operate the transmission equipment in the regulated higher frequencies, and the rules are written especially as guidelines for us brains to go by in exercising our program business.
Wearing a hardhat helps shield the brain from flying objects, like out of control hobby drones.
Playing football or soccer may be harmful to the brain.
Join me in thinking about this.
