I cannot countenance risk assessing something that can kill without putting into place any and all accommodations that will reduce that risk level.
There is an extremely small, but still finite risk that you could be hit in the head and killed by a small meteorite. Years ago a woman in Alabama was injured by a meteorite after it came through the roof of her house. (See Sylacauga Meteorite.)

Since you believe in taking "any and all accomodations" to reduce risk, I assume you have installed a steel plate in your roof, and wear a balistic helmet at all times when you are out of doors?
