LOL. I was huge raver from ~18-22 and saw lots of that type of stuff from both natural and un-natural mania. I had a friend once who had a (natural) manic episode and wanted to get rid of a non-running car in his garage. He cut the car into small chunks with a large Dremel-type tool and threw it away in the dumpster. I mean the entire car. This took about 48 hours. The dumpster was so heavy they had to bring a special truck, and someone had to ask who threw away a car. I think the apartment complex forwarded him a bill for special industrial trash removal. HN-worthy nerd tangent: Remember all the discussion a while back about the threat posed to humanity by runaway self-improving AI super-intelligences? I've always thought that you don't need a super-intelligence in the IQ sense. You just need something with the intelligence of a moderately smart human with super-focus and super-motivation. Imagine something that ran by default in the state you describe above but with no cognitive impairment side effects. That would be super-human. A "race" of these would find conquering humanity trivial even if their IQ-type intelligence were merely comparable to ours. Most humans exist in a state of low-grade depression most of the time. I have for years thought that the dopamine pathway is the rate limiter for human achievement, not IQ or memory or anything else. It's one of the many reasons I'm a moderate IQ skeptic. Our reward/motivation system is calibrated for a very slow hunter-gatherer lifestyle. The problem is that we have not found a good way to artificially boost this without side effects that impair cognition in ways that result in things like dumb comments on Twitter that get you in trouble with the SEC. Amphetamine|coke|mania is a helluvadrug.
