Beware power tools, and many unpowered tools as well.
Two weeks after moving to Arizona I was removing some excess foliage in my back yard when a 10" electric chain saw attacked me without provocation. That led me meet Dr. Shere Khan (REALLY) at the VA emergency room. Dr. Khan is a great doctor but a terrible tailor....lousy stitching, but it worked. Over the next eight years I've kept him busy with other injuries, but none have involved power tools because I got very careful.....pronounced "paranoid".....after that.
