All of those things you listed do not deterministically kill you as soon as things go wrong. Plenty of people survive car crashes, shaving, eating too much or too little. Even people who accidentally choke on food survive in a lot of cases. Plus, people do those things in order to either live (eating) or to enhance their life experience (shaving, airplanes). I am yet to hear of someone surviving after their heart or liver was removed for donation from their body. And I am also yet to hear of anyone donating their organs in hopes of enhancing their life experience.
