This question is ambiguous and could be interpreted in a few ways. To provide the most helpful answer, let's examine the possible meanings:
1. Public Transportation:
- If you are asking about subway or train service running after midnight, the answer depends on the specific city and transportation system. Some cities have limited service overnight, while others run 24/7.
- To find out if tubes (subways) run after 12 in your city, consult the official website of the local transportation authority or use a trip planning app.
2. Medical Devices:
- If you are asking about medical tubes, such as IVs or catheters, they are usually left in place for the duration of treatment or until a doctor determines they are no longer needed.
- The length of time a tube remains in place varies depending on the medical condition and the type of tube.
3. Other Interpretations:
- There might be other contexts where the phrase "tubes" is used, making the question even more ambiguous.
- It's important to provide more context to get a clear answer.
