I agree on sharks (depending on the kind of shark and the way it's caught). Salmon sharks always come up in the net while we're salmon fishing. They're vicious little thrashers; the manly thing is to let them go (not many people do; they kill them out of spite and boil their eye balls for their marble collection).
Sleeper sharks are fat, bloated, docile sharks that sometimes get caught in long-line gear. One year, about 20 of them died in our long-lines, the other 30 or so just sat their calmly while we untangled them. It was kind of sad.
Burly accomplishments:
-wilderness survival trials (ie go out into the woods with just a knife and a set of clothes.) Of course, practice safety (bring a cell/sat phone in case you screw yourself over. dumbass attacks happen to the best of us. How you approach a survival trial depends on your flavor of wilderness (coastal, boggy, woods, mountain, desert, etc.) so you should be familiar with the climate. In fact, I wouldn't do this at all without region-specific survival training first.
-polar bear swimming (I could never do this, cold water knocks the wind out of me; I can't keep air in my lungs.)
-Get on a crab boat and do the Bering sea at least once. Don't quit halfway through the season.
-Take control of a bubble market, guide it to a safe deflation.
-Hold political office and clean a neighborhood up.
-Rehabilitate extremely dangerous prisoners, help them integrate into and synchronize with society, turning at least one of them into a monumental positive impact on society.
