having somebody yell at us in the office or by making a mistake or losing a bunch of money. these aren t problems that our hunter/gatherer ancestors had. they would get stressed if a lion was coming after them or a bolder coming toward their living quarters. and that kind of stress provoked the fight or flight response. getting you ready to do something. weekends! yes. but your mother cannot know there is plenty of stress and adrenaline on stage at the groundlings theater in los angeles. does the doctor know that you re out here? i m sorry, what? this is improv comedy. and hardly anything that can make you more vulnerable and tap into your creativity.
