Sure some of it is wrong, sure kevin exagerates some things, sure he is definatly in it for the money. Whats wrong with being in it for the money?
I will tell you whats is wrong. Much of his advice is not only wrong, but downright dangerous. Both in what he recommends and in his views against the medical community.
His idiotic stand on skin cancer is known and proven to be wrong, yet you will find many who believe him. Putting themselves and possibly their children at risk by following his advice.
His claim of false "cures" based on natural items, also places people at risk, who may postpone medical attention in a foolish attempt to heal themselves.
