Is the economy and school system trucking along?
Is the "green pass" system in use anymore?
You really shouldn't subscribe to this 'seat belt' theory (many people die every year despite wearing seat belts hence seat belts don't work ... yet you wear them).
Any update on the monkeys that went missing? What town are they nuking?
