Here's something I didn't know...

...about Warren Buffett:

Among those who seem to have reached a similar conclusion is Warren Buffett, the wealthy chairman of Berkshire Hathaway. Mr. Buffett separated from his wife, Susan, in 1977 but remained married to her until her death in 2004. All the while, he lived with Astrid Menks; they married in 2006. The threesome remained close, even sending out holiday cards signed, “Warren, Susan and Astrid.”
