It's just an exercise to estimate your own value of life. There will never be a button but there will certainly be times in your life where you will be given the choice to take survival risks for certain benefits. People who enjoy motorcycles are accepting a very large risk of a nasty and most likely painful death at a young age, but they love riding so much that they are fine with that risk. Same for people who smoke cigarettes, eat excessive amounts of fried food, or take part in copious amounts of unprotected sex with multiple partners.
