Final answer:
People attracted to BASE jumping enjoy the adrenaline and dopamine-related 'high' elicited by the sport's inherent danger. Conversely, those who are risk-averse or shy may not find such extreme activities pleasurable due to biological differences in stress response.
Step-by-step explanation:
Some people are drawn to extreme sports like BASE jumping because they crave the adrenaline rush it provides. The release of adrenaline triggers a fight-or-flight response which is closely linked to dopamine, a chemical in the brain associated with pleasure and addiction.
This can lead to the experience of a euphoric 'high' that adrenaline 'junkies' seek out. These individuals might be inclined to participate in risky behaviors or take on challenging jobs to satisfy their desire for this rush.
On the other hand, certain individuals may be more risk-averse or shy away from such extreme activities because the potential danger and the stress response it triggers are not experienced as pleasurable. This divergence in behaviors is often based on biological differences in how people's bodies and brains respond to high-adrenaline situations.
