5 highlights from Bill Gates' interview with "CBS Mornings" as he looks to his "last chapter"

Billionaire businessman and philanthropist Bill Gates is giving up his wealth for the health and wellness of millions, announcing exclusively on "CBS Mornings" on Thursday that he's committing $200 billion from the Gates Foundation to be spent over the next 20 years.

Gates first revealed his plan to give away virtually all of his wealth in an interview with "CBS Mornings" last week, saying he will take an "equity, value-driven approach" to the distribution of funds. It will go toward several causes, with a focus on global health and education. His ultimate goal: save tens of millions of lives, especially those of women and children suffering from HIV, malaria and other deadly illnesses. 

Here are some highlights from his discussion about his $200 billion mission, as well as what he calls his "last chapter" in life – and more.
