4. She makes Mark a better man
Chan inspired Zuckerberg to start an organ donor program on Facebook. In May, the company announced that members could share their donor status and register to become a donor. “Our dinner conversations are often about Facebook and kids, and the kids that she’s meeting,” Zuckerberg told Good Morning America about Chan. “She’ll see them getting sicker, then, all of a sudden, an organ becomes available, and she comes home and her face is all lit up because someone’s life is going to be better because of this.”
