Parasitic worms often have elaborate mechanisms to hold onto their feeding site-- the skin, intestinal wall, etc. Doctors have examined this method and are using it to keep skin grafts in place. See here.
One of the amazing things about the brain is how everything connects to everything else. We all have a problem visualizing that. Here's a solution.

Ezra Klein points out that doing our taxes is hard. It doesn't have to be that hard. And there are vested interests in making it hard. See here.
