I spent a month researching that story and did several follow ups. The very smart guy who pointed me toward Brain Doctor was former USC quarterback Paul McDonald. UCLA (Coach Terry Donahue) used him and so did many other people I respect....But like I said, it's not foolproof.
@DufRankman I just read the accompanying article instead of just the blurbs. This guy is a crackpot if he's associating physical skills to Meyers Briggs personality types, which themselves are bogus. How do these shady people get organizations to pay them and trust their word? SMH 🤦♂️
