Not sure who needs to hear this but we all know that a zinc deficiency lowers our immune system. Here is one of the leading causes of zinc deficiency.
Frequent sex and masturbation can be one of the key causes of zinc deficiency. David Horrobin, M.D. and Ph.D. from Oxford University, declared that, “The amount of zinc in semen is such that one ejaculation may get rid of all the zinc that can be absorbed from the intestines in one day. This has a number of consequences. Unless the amount lost is replaced by an increased dietary intake, repeated ejaculation may lead to a real zinc deficiency with various problems developing, including impotence… It is even possible, given the importance of zinc for the brain, that 19th century moralists were correct when they said that repeated masturbation could make one mad!” Also Carl C. Pfeiffer, Ph.D., M.D., in his book on zinc stated: “In a zinc-deficient adolescent, sexual excitement and excessive masturbation might precipitate insanity.”
MAD, adjective - "disordered in intellect" aka lack of comprehension based on ignorance to resist temptation aka choice of want over need.
What other old wisdom has been thrown out with the bathwater?
WISDOM, noun - "use or exercise of knowledge (perception)". Perception isn't old; those perceiving (form) are aging within all perceived (flow). Aging represents corruption of memory storage for comprehended knowledge aka one still perceives all inspiration; yet has less capacity to comprehend stored information and diminished potential to respond to all perceived inspiration by choice.
That represents an allegory for form (bath aka place for bathing) being transmuted back to (thrown out) flow (water).
That you can shower outside the bath; which keeps the bathwater clean enough to be used in the garden afterwards (after going through a charcoal filter if it's tap-water mystery juice).
