One man, Warwick Powell, has a T-cell count so low that, technically, he has full-blown Aids, but he will not take the antiretroviral drugs that would keep him alive. The Bank has taken every penny he had: 'I've spent my entire fortune,' the 40-year-old concedes, 'and then some.' By late last year, he was £30,000 in debt. After 12 months of utter devotion to the process, his promised recovery of T-cells has failed to materialise, but the instructors' glib faith in the curing powers of their platitudes persists. 'Warwick,' one of them assures me, in the manner of someone stating the mindblowingly obvious, 'is not HIV positive. There is no such thing as illness - only energy blockage. He just needs to give the energy more time.' What if the Bank fails to cure him? 'It would not be the energy's fault,' he replies. Warwick thinks, in other words, that it would be his.
