There are steps to minimize being hit with deadfall, but there's no 100% solution, even when hiking.
A fellow backpacker who lived in this area was backpacking with a friend and, during the hike, deadfall hit his friend while walking; this hiker died at the scene, far from medical attention. Freak accident. You can't live life pausing at every tree you walk under though. Devastating for all involved, so condolences.
Still I will take my chances with the outdoors as I observe other drivers texting while driving - while simultaneously smoking or eating, racing like the movie "fast n'furious", or just driving in a rage. Or sitting on the couch after a day of work sitting at the terminal. One thing for certain, our chances of death are always 100%, so might as well enjoy life while here.
