personal stupidity

Today I learned that the park service closed some of the trails I like to walk on because there's a mountain lion hanging around that part of the national park. Then, since I took a different set of trails this morning - trails that had actual hills in them - I learned that if you trot up the water-bar stairs because you think you're in good enough condition, you can shake something nasty loose internally and end up a detox idiot for the rest of the day.

Thus the only other thing I learned today that stuck was that there's a company in Japan that made a powered exoskeleton that helps a person be really, really strong, so it's kind of like that loader thingy Sigourney Weaver used to kill that alien in Aliens. But they named the device HAL, like the homicidal computer in 2001: A Space Odyssey, and their website is www.cyberdyne.jp, like the company that made the computer that killed everybody in Terminator.
