An article in the Home section of the New York Times about a Brooklyn house owned by the musician Mike D of the Beastie Boys and his wife filmmaker Tamra Davis carries the following sentence:
Mr. Diamond, who prefers not to give his age, now has two boys of his own, Davis, 10, and Skyler, 8, with his wife, Tamra Davis, a filmmaker, who also prefers not to give her age.
Plenty of other people the Times writes about would prefer not to give their ages, but the Times either figures them out using public records and puts them in anyway, or just leaves them out rather than making a big fuss about it. It's hard to avoid the conclusion that the Times gave Mr. Diamond and Ms. Davis more flexible treatment in exchange for being allowed into their house to do an article about it for the Home section.
If the paper is going to cut those kinds of deals, some more transparency would be great: "We agreed not to print the couple's ages because they threatened to kick us and our photographer out of their house if we insisted on it, and then we'd have to find some other people to write about, which would be more work."
Wikipedia says Mr. Diamond is 46.
