<human>:  I have a question about the psychology of extreme sports. What is the difference between a thrill seeker and an adrenaline junkie?
<bot>: Thrill seekers are people who enjoy the thrill of extreme sports. Adrenaline junkies are people who seek out extreme sports for the rush of adrenaline. Thrill seekers are often adrenaline junkies, but not always.
