“My hair would continue to gray, and then one day, it would fall out entirely, and then, on a day meaninglessly close to the present one, meaninglessly like the present one, I would disappear from the earth. And all these emotions, all these yearnings, all these data, if that helps to clinch the enormity of what I'm talking about, would be gone. And that's what immortality means. It means selfishness. My generations belief that each one of us matters more than you or anyone else would think.”
