Hubbard received a gift of a bed and complained about the metal nails in the bed. He had some kind of allergic reaction to the metal nails, at least in his mind.
He was bothered by tiny dust particles in the air and by smells no one else could perceive.
He was bothered by what he thought was the odor of soap. He ordered his child servants to scrub his clothes, by hand, in a bucket, and rinse his clothes, in 13 separate buckets.
But, somehow, he couldn't have a super sensitivity to the current of an e-meter?
There are people who used an e-meter - interacting with its electrical current - for decades. It can become a habit. Extreme sensitivities can occur.
Towards the end of his life, Hubbard demanded that an e-meter, with increased current, be made, especially for him. It was interpreted as a death wish, but was it? Hubbard expressed a need for more electrical current.
