Yes, and at any point of your life, you can get hit by a bus, struck by lightning, choke on a sandwich or die in an earthquake. By all accounts, people should constantly be running and screaming on the streets, hoping a disaster won't strike. But I think most people understand life is a lottery, even those who are trying to reduce the chances of something bad happening.
As for being in shape / working out, it isn't just about your health. It's a stress relief and a confidence boost too. It's also considered attractive, shows dedication and discipline. So you might get more out of it that simple weight reduction and muscle increase.
