Depends on your definition of "avoid".
Technially you could "avoid" death by not riding a motorcycle, driving a car with ***** saftey ratings, not participating in dangerous leisure activities like freestyle mountain climbing, base jumping, swiming with great white sharks, staying out of potentially hazardous locales such as Gary, IN, Southern Chicago, East Saint Louis, ect.
The point is, you can reduces your chances of probable reasons of death, but you never eliminate all of them. In fact, you could be concentrating so much on the imposibles, you may be neglecting the probables.
