Wel-l-l-l-l...I'm not too sure I want my molecules massaged in public. You never know who might be watching/listening. ;o]
When I get hungry for the human voice, I put on some of my favorite music. Some is sung, some is not.
I think my mother decided I was so independent I didn't need human contact. Go figger. One of my jobs was as a telephone CSR. *snort*
Massaged molecules are far too small to be seen in public, your voyeur would need a high powered microscope pressed against your flesh to see certain ones dancing at given sound frequencies. As to your “hunger” for the human voice and the music alternative, you make the case : certain molecules NEED some jogging/massaging and await the right note to get them dancing. Everyone needs to be noticed/loved, even body molecules. So crank up the volume and LUVEM.
