Host Brad Kearns talks about the importance of tracking testosterone and other key blood values, and how we can have a tremendous and immediate influence over our blood values without having to resort to medication regiments. Brad mentions how he doubled his testosterone level, going from clinically low (and candidate for drug therapy) to beyond 99th percentile for males over age 50 six months later. The first reading was after several months of "chronic cardio" in the form of frequent Speedgolf. The second reading came after months of rest and recovery following a string of surgeries. The story comes with an important message about getting help when you are in pain instead of trying to tough it out like a tough guy. Brad's medical ordeal of an emergency appendectomy and months of complications and a few additional surgeries after could have been much less troubling had he insisted on further medical care instead of toughing it out. A few athlete Q&A is also included, including how "180 minus age" is a great reference for training, but not too relevant for a short sprint race.
