 And I've been practicing medicine now for over 40 years. And these are tests that I do on patients usually twice a year. And we simply optimize those hormone levels. We check them for prediabetes. We check their complete blood count, their comprehensive metabolic panel that checks their livers and their kidneys and their electrolytes. And it's amazing how many people with fatty liver I find. I find fatty liver every day in patients due to the high sugar intake and the high carb intake.
