I want to hear your thoughts and fuel this discussion. Pain caused by loss of blood or oxygen is an alert signal rather than an external sensory message.

Physical scientists, particularly physicists and chemists, made important contributions to an understanding of the nature of stimulus energies e. He held that this system subserves pain and the extremes of temperature and pressure sensation usually associated with an affective emotional tone.
