Something that is not yet known to be an indicator that you’re at risk of a condition.

Perhaps you were given some medication that is later proven harmful. Maybe there’s a sign in your blood test results that in future will strongly correlate with a condition that emerges in your 50s. Maybe a study will show that having no appendix correlates with later issues.

How confident are you that the data will never be used against you by future insurance, work screening, dating apps, immigration processes, etc
