muscle cells or your brown fat cells to these kind of like healthy stresses exercise cold and heat exposure it's going to make them uh better at like activating and also um at keeping you healthy so as long as the the cells get exposed to this it's going to keep them on its toes you can say because it becomes more robust um increasing these heat shock proteins and cold shock proteins in the cells to um make you more robust for the next time

these environmental micro stresses you know the heat the cold the exercise the oxygen starvation for a short amount of time anyway you're gonna embrace inconvenience
