Documentary unit: pieces to camera

After a thrill the chemical dopamine is released, which acts like a natural high. so it's easy to see why people chase it. It is thought that adrenaline junkies, or sensation seekers, get a larger
amount of dopamine than people who have low sensation seeking behaviour.
Roller coasters are one of the most popular thrill attractions. They still make us feel
apprehensive, even though the chance of being injured is only 1 in 24 million.

I’m here at the London Tombs to meet Kirsty, who has worked here for 5 and a half years to see
what she can tell me about fear.
So the tombs were definitely a more interactive and simulated horror experience, and i'm
starting to get a feel for it, but i still want a more extreme feeling. So Im meeting Jackie, a
seasoned adrenaline junkie, to see why she keeps coming back for more.
I quite like health and safety, but i don't think Jackie does. So maybe that's why she is much more relaxed than i am about this jump. I definitely feel a lot more fear than i ever had in a theme park or horror maze, but this just feels more ‘ real’. This is the closest i could get to facing our most instinctual fear, falling.
