I bought a loggers helmet to use when chainsawing; it has earphones and a metal mesh face screen. Today when I was chain sawing firewood, a chunk flew back and hit the helmet, saving me an indeterminate injury. Skateboarding in San Francisco at night a few weeks ago, I had on all my safety gear and when I hit a deep crack in the pavement, my board went backwards and me forward and I skidded along the pavement on my hands and knees, protected by respectively, gloves with hockey pucks for palms, and sturdy knee guards -- no skin lost.
A 3rd thing I'm doing is using MacSpeech Dictate (Dragon Naturally Speaking for Windows) more frequently all the time to cut down on wrist tension from computer work. Two years ago, I had carpal tunnel surgery. The physician, Dr. Robert Markison, is a remarkable man in many ways (write me if you have wrist numbness etc. and want details on Markison); he recommended the software and it's surprisingly good . I also switched my mouse to the left side and have taught myself how to use it. All of which is cutting way down on computer-generated tension/stress on hands and wrists. (Fits safety equipment category in the sense that it prevents injuries.)
I'm getting more conservative. I figure I've been lucky for all these years and injuries at my age are no joke.
