I don't know what was true here but I do know that children don't get myelinated at 25, if you have a de-myelinated brain you die, it's essential to insullate neurons from themselves and so as soon as he said that kids don't have myelin until age 25, I discounted everything he said. Which is unfortunate because a lot was compelling.

E.g., unless someone wants to tell me that adrenoleukodystrophy is a made up children's disease with evidence, then as far as I'm concerned Kruse is full of shit.
