Older, younger? Wow. That stuff made me clench my jaw. I only used it a few times, couldn't tolerate it. Very strange at first. I know this old guy who started a major record company in toronto, and has sons in law school in america, he tolerates it and is like 73 or something. But that's possibly rare. -- he owns a dry cleaning company now. ---Amps do kind of remove a person's soul at times. Not easy to get off.
