A recurring conversation I have with a healthcare worker friend is that if you had no conscience, an easy way to make money would be to peddle innocuous but inutile items by marketing them as wellness products.
Scientific language can be so impenetrable that a few vaguely therapeutic-sounding buzzwords are often enough con people into parting with their money – in the case of alkaline water, for example, or IV vitamin drips, or vitamin supplements in general.
