There are sceptics than believers out there. It is a cynical world ... human nature. "because I don't have it I don't believe it, attitude. Appreciate it as information and when one decides to head this path, one is well informed. That's what forums are all about to me ... share information, experience and help each other out. Not ridicule people without trying out something. Unbelievable!
