Suppose there is a button in a convenient location that, when pressed, causes you to die in precisely 20 years. When you press this button, you will remain in the same state of health and be completely immune to death by accident or murder until you suddenly expire in exactly 20 years, to the second. The only way to die before the 20 years are up is to commit suicide, do something spectacularly dangerous, or attack someone and get killed in self-defense.
So, knowing all this, when do you press the button? How do you change your way of life after pressing the button, or how do you live differently in preparation for the moment you press it? Knowing your moment of death, how would you act in the days just before?
Edit: I repeat, WHEN do you press the button? That is the main question. Age 25, age, when do you decide to press it? You can press it multiple times, but you'll die 20 years after the original button press.
