Besides "crashes" the risk of dying from the effects of flying are Looong run and therefore most people ignore them. It is like smoking, doesn't kill anyone right away, it is cumulative. Pilots and flight attendants obviously get the worst of it.

People who fly as much as you seem to should also be concerned. There is no personal protective equipment that I know of that you can take on the plane.

Are you concerned when your drive a car? It is risky too. Again for those who drive huge miles, lots of physical risks are incurred.
