The thing is, for that glove to work, it must complement aspects like physiotherapy and rehabilitation, particularly during the early stages of a stroke. Jack, who always wants things (and FUD) NOW NOW NOW NOW! probably believed that the glove was a panacea for curing his stroke and simply gave up because "it didn't work immediately." Not only did fatty refuse to follow up with physiotherapy and rehabilitation early in the stroke, except for when he was forced to do so in the nursing home, but he has also repeatedly disregarded his doctors' advice. Instead, he only listens to his brother Charles for stroke advice (e.g., adopting a carnivore diet to heal himself), for some bizarre reason holding his brother in extremely high regard.
