 is also the adrenal glands. The adrenal glands are the body's stress glands. And if your body is not managing stress well, your adrenals can get pretty exhausted, pretty tired. And when the adrenals get tired, that's when you get tired. And that's when everything begins to shut down and not work that well. So that's one thing I would want to encourage you for is to make sure that you're giving the body everything it needs and that these different systems are not breaking down. That's why blood testing is so important. Saliva testing can be important too.
