The subject of hair comes up in this as well. Since our hair is an extension of our central nervous system does it pick up the electrical impulses while in the shower or bath and interpret them for us??? What information is our hair actually picking up in and thru the water?

"That the neural factors play key role in the hair growth process is proved by the fact that the hair follicle is richly innervated. The follicular growth cycle coincides with a constant remodeling of these innervations..."

Intriguing article about the way the hair in the ear works to cause us to "hear" sounds:

The six features that characterize the ear's active process are signatures of any dynamical system operating near a Hopf bifurcation (17, 18, 38). That active hair-bundle motility displays those properties therefore does not preclude the possibility that the ear contains oscillators in addition to hair bundles. The similarity of the active process throughout the vertebrates, however, suggests that a common amplificatory mechanism is at work in all mechanically active acousticolateralis organs, the mammalian cochlea among them. It is probable that active hair-bundle motility is essential for amplification and in fact constitutes the active process.

Upon depolarization, nerve fibres expose their neighbouring cells to a multitude of neuronal signalling molecules, such as the neurotransmitters acetylcholine and noradrenaline or the neuropeptides substance P (SP), calcitonine gene-related peptide (CGRP), peptide histidine methionine (PHM), neuropeptide Y (NPY) (Table 1) and many more (8,9). The discovery of these signalling molecules has taught us that there is more to neuronal activity than the basic afferent and efferent exchange modalities between the periphery and central nervous systems. New insights into this discovery are accumulating on an almost daily basis (5,10–12). Through close contacts to and communication with a wide variety of skin-related cell types (Table 1), nerve fibres display a plethora of biological activities from growth factor activity (13–23) to immune modulation of inert and specific cutaneous immune responses (24–32). Recently, these insights have been applied to a number of cutaneous diseases, such as atopic eczema and even in the analysis of cutaneous stress responses."

This also leads into another direction of thought for me as well. Wonder if certain archeological artifacts would hold certain geometric structures if placed in water and then view under a microscope if that would answer some questions as well.
