Industrial robots have an amazing number of specialized hands that can be used in a
wide variety of jobs. They can pick heavy things up, or manipulate the most delicate
of microchips. They can drill holes, operate spray painters, and tighten bolts. Even
with all their capability, robotic hands are simple when compared to an artificial
human hand. Robots do one job over and over. On the other hand, Humans use their
hands to do many different jobs. Robotic hands can be arbitrarily heavy since the
robots don't get tired. Heavy prosthetics can be extremely uncomfortable and cause
injury to the area where it joins with the arm. The human hand has 27 bones and can
make a number of complex movements and actions. Robots working in industry need only
the relatively limited motions dictated by their specific job so they can only
clutch something in a single type of grip. Robotic hands, once they have grasped an
object, don't let go until they are told to do so. A human using a real hand to
grasp something simply involks the 'keep holding until I tell you to do something
else' behavior in their subconscious, so that a human using his real hand can walk
and hold a cup of coffee at the same time. By contrast an advanced artificial hand
requires much more conscious attention from the user to make sure the object isn't
dropped. See more ...

For about thirty years, I showed, felt, questioned, and tried to investigate what I didn’t realize were what 13 to 14 million people experience in any given year: the signs of depression that have now been studied, therapeutically dealt with, and successfully treated. Before I knew that ADD (Attention Deficit Disorder) was my personal albatross weighing me down perpetually and daily, along with the symptoms of depression that are very typically present in ADDers, I had a hell of a time staying on the planet. I had to drag a heavy (emotionally and physically) carcass out of bed, where I preferred to or was compelled to stay. I found it futile to make that bed, as I would just be climbing into it again. I found most activities—those I had a passion for in better days—dull, useless, trite busy-making atrocities. I was bitchy or crying. (Toward the end of the thirty years, I cied every day and for hours.) See more ...

Sleeping disorders are the WORST. We all know it (even if we havenÂ’t yet, thankfully, had to actually experience them). People all the way back in history have bemoaned the trials and tribulations of sleeping disorders. Many have conquered problems and developed tricks or habits for sound sleep patterns. Rare sleeping disorders are written about and made part of fine films. And artists, poets, and musicians had sometimes unusual relationships with their nighttime habits. See more ...
