Something to keep in mind is that adrenaline is something used in medication to treat ADHD in some cases. The desire for some to go out and do things like this (ie: Base Jumping) could be sourced to them craving that adrenaline that helps them focus. Maybe they are taking the wrong type of medication or maybe they aren&#x27;t taking any at all.<p>Additionally I found this part very frustrating<p><i>&gt;&gt;Panksepp points out that while common stimulant medications for ADHD like Ritalin and Adderall may improve attention skills and academic performance in many kids, they do so at the cost of reducing the playfulness urge—at least temporarily. “We know these are anti-play drugs in animals,” he says. “That is clear and unambiguous.”</i><p>This is strongly anecdotal but as someone who takes Adderall, I can&#x27;t say this could be any further from the truth. The only thing that I can come up with that could lead to this thinking is that younger kids who have trouble with their hyperactivity might not be as hyper anymore after taking medication (which was the whole point in the first place for some). All this is doing is encouraging more adrenaline junkies to treat themselves outside of conventional means.
