If you don't want to get tracked, make sure to not wear your face or body in public. Where I define "public" as places where you can be seen.
If it isn't obvious: this post is a mix of reality and irony. For the last ~50,000 years, humans have not had absolute privacy in public. The moment they can be seen, they can be identified, and therefore track. The only change is that the technology for identifying and tracking has become more accurate and efficient. Even 2000 years ago, a sufficiently powerful adversary could station enough of their henchmen at every corner and every tree in the forest to find you.
