Being open minded about issues like this is worthwhile. Many people really close off when even confronted with the possibility of curing AIDS, especially medical practitioners. They'll tell you about how bad and incurable it is. I feel that people ought to have more faith in themselves. You can't claim to cure anything these days without a medical license, and doctors certainly can't cure much either.
If someone is trying to persuade me that there is no cure for an illness (which they have before) often what I hear behind their words is a suspicious agenda, whenever someone talks like that there's usually more to investigate. It's unwise to take absolute claims at face value.
