Advertisers would get their hands on your data and figure out you’re predisposed to certain foods and stress eating. With that information, they can tailor ads more specific to your genetic traits.

Thank god for privacy laws! No corporation has ever violated those for profit. And laws never change, right?

In Canada, the least-trustworthy people I've ever dealt with have been medical doctors, lawyers, politicians, bureaucrats, or some mix of those.

I can't trust such people to put in place and operate any system that truly protects medical privacy.

Or, if you're unlucky, more expensive insurance in the future if you're high risk.
