Ben, pat yourself on the back... you potentially thwarted a world renowned, best-of-class spy agency from collecting invasive personal data from your very lifeblood, your children.
This may be the difference between your kids being ordinary nerds taking pictures of themselves hiking through a wildlife sanctuary while uploading their location to foursquare and being falsely implicated in a plot to overthrow the government and thrown into Guantanamo Bay.
And thankfully, you didn't stop at merely declining getting your kids' DNA tested, ignoring the peer pressure of all your cool yuppie friends who did so with their kids. Instead, you blogged your decision, and thereby recording your extreme intelligence and wit in a free permanent form for the masses to consume and benefit from.
I salute you, sir. A freedom fighter to which we all should bow to.
