You might be surprised how many old people commit crimes. They aren’t tagging houses or robbing banks and museums (usually) but they can do a lot of other things. Petty theft, drunk driving, sexual offenses, etc.

And the effect of lead is subtle, like toxoplasmosis. It’s not a ‘touched lead, now I’m guaranteed to become a serial killer’ effect. It’s more like the lead dulls your ability to think ‘I probably shouldn’t do X,’ so you have a higher probability of doing things that get you into trouble.

The only thing that changes is the number of people and institutions that hold you responsible for your actions. No more chance to be tried as a juvenile for crimes. Fewer people will say ‘ah, they’re just a kid,’ if you make a mistake. Your financial decisions are more likely to follow you. Etc. Etc. You won’t feel different, but the expectations will be there.

I’d have to spend a long time travelling just to find the answer to this question.

There’s no cheat code to get them to like you, dude.
