How can a person live without love?

You don't love someone out of loyalty... nor out of sympathy, either.

People, you see... are ruthless and foolish. When they're young, in order to have money and power, they give up everything like health and youth. And when they get sick, become old, and have all the money and power... in order to find their health and youth again, they spend all of the wealth they've wasted so much energy and time to accumulate.

If you consider it valuable, it will grow valuable.
