Anterior Midcigulate Cortex Growth

Will power has been a topic on the podcast recently and it was expressed that doing something challenging and particularly doing something you don’t enjoy will actually grow the AMC as fascinating as that is. I’m curious if there is any evidence that the anterior midcigulate cortex grows when we refrain from doing something we derive delight. As a recovering alcoholic, willpower, discipline and self-control are very attractive behaviors. The phenomenon of craving is often very uncomfortable but let’s say one refrains from their DOC(drug of choice), would this then grow the AMC contributing to one’s willpower in addiction?

Andy Galpin Blood Marker

I believe Dr. Galpin said, rather casually, that if he saw one blood marker above a certain level, that's all he needed to know that the person was fit. It wasn't the typical Galpin multi-faceted answer, but I forgot what that marker was, and what the level was. I tried to search through his six part series but couldn't find it. Was it Hemoglobin? It was something relatively straightforward. By the way, I'm a big fan of the work you do, your approach, and your humility. Eunu Chun
