OK, this isn't limited to JUST JW"S, but my gawd it seems like there is always a subcult in every congregation that follows some sort of QUACK ALTERNATIVE MEDICINE or PYRAMID business scheme.
I met an "iridologist" who reads your eyeball like a palmreader then prescribes high $$ herbs - usually some sort of colon cleanser concoction.
I met a quasi massage/chiro-healer who can cure anything through chiropractics.
I met dubs who swear that all you have to do is hold medicine up to you abdomen to see if it 'reacts' to you body to determine if you need it.
I know dubs who swear they will retire early and pioneer from the profits of AMWAY or EXCEL Telephone or HERBALIFE or MELALUCA or some other stuff like that.
Herbs, minerals, Amway and nearly all other 'sucker-schemes' - that gets my vote.
