The new “it” event? Celebrity spit parties are all the rage, hosted by 23andMe, a company co-founded by the wife of one of the guys behind Google. The company sells do-it-yourself genetic testing gadgets at $399 a pop, claiming to uncover info on nearly 100 DNA markers by analyzing…well, loogies. (Take that, Party Monsters: Cabo!) 
TIME magazine bestowed the honor of 2008 Invention of the Year on this nifty little DNA testing kit. But finding out if you’re prone to Parkinson’s disease or multiple sclerosis or colorectal cancer or age-related macular degeneration? Um, doesn’t exactly sound like a barrel of laughs to us. Bring on the Pictionary! But we’d love to make the invite list just to have the opportunity to see the likes of Ivanka Trump (The Celebrity Apprentice, NBC) drop saliva into a test tube. It gives us giddy thoughts of enrolling her in VH1’s Charm School.
“I have a very low chance of becoming obese,” said The Donald’s daughter after hocking one up at a recent spit-fest. “That makes me exceedingly happy.” Yeah, Ivanka, we’re jumping with joy.
“Ivanka is right that genes are important for obesity,” says geneticist Claire Haworth, King’s College, London. “However, the DNA test 23andMe offers only looks at one particular gene associated with obesity risk. There are some other genes we already know about that contribute toward obesity, and there might be even more we don’t know about yet. Also, it’s not all in the genes. Lifestyle is equally important, and so is the interplay between genes and environment.” Say it; don’t spray it!
