Welcome to a preview of the 15th Ask Me Anything (AMA) episode, part of Huberman Lab Premium. Huberman Lab Premium was launched for two main reasons. First, it was launched in order to raise support for the main Huberman Lab podcast — which will continue to come out every Monday at zero-cost. Second, it was launched as a means to raise funds for important scientific research. A significant portion of proceeds from the Huberman Lab Premium subscription will fund human research (not animal models) selected by Dr. Huberman, with a dollar-for-dollar match from the Tiny Foundation.
