Luckily I had no severe biomarkers. Some minor ones, but nothing I didn't know already. I loved learning about my ancient ancestry, though (ie migratory patterns 300k years ago.)
On balance, was the utility worth the cost (of a breach)? Probably not, because I found no major actionable issues. But if I did find severe biomarkers, it would have been worth it. So I do still think I made the right choice.
