23andme goes free for today: DNA testing, disease risk analysis

Knowing nothing more than what I've read in articles elsewhere, to someone who's not going to have a child immediately, these kits provide information that is of limited use. For example, they might tell you that you have a 10% higher chance of developing a type of cancer which has an incidence of 1 in 10 (10%). Implying you're now told that you have an 11% chance of getting the cancer than the general population. Mostly, this is just going to get you stressed and not "prepare" you to face the slightly-more-likely cancer.

I suppose this might be useful to figure out potential genetic defects, but as adults, wouldn't most defects have manifested already (I'm speculating here, correct me if I'm wrong).

The title is a bit misleading. You get the kit for free if you sign up for their $9/mo "Personal Genome" service.

Its still cheaper than before, but not _free_.

lie.

from $199 to $108.

very different from free.
