WANTED: suggestions for an adrenaline junkie

[starborn_scribe]

A character in a story of mine is quite the adrenaline junkie. I am not. Hence my plea for help for ways to show that the character does things for the thrill of it. He's a working class white American, athletic, mechanically adept, in his late 30s, and lives in a West Coast city.

Here are all of the activities and occupations I could come up with, regardless of whether they fit a city setting. Do you guys like any of them in particular? If you can think of any more please comment. Thanks!
