Ben Greenfield offers a brief first-person update on his experience using the Under Armour mouthpiece during various workouts (swimming, cycling, running, lifting), reporting reduced perception of discomfort and claiming it may lower stress/cortisol and pain by keeping the TMJ open. He recounts a listener (Brad) who reported claiming the device on insurance as a sleep aid, paying $65 of a $495 price, and says he'll try it for teeth grinding. The video is an informal testimonial-style product update with practical tips and anecdotal evidence.
