How do I check how much is on my Oyster card?

You can find out how much money you've got on an Oyster card at ticket machines by holding your card against the yellow Oyster card reader. Or you can check your balance anytime online if you register your Oyster card and have an account. If you haven't already you can do that on the TfL website.

What are the benefits of having an Oyster card?

The advantages of an Oyster card are that you can top up your credit online and add an electronic 7 Day Travelcard onto the card. You can also get an Oyster card before you arrive in London if you live in the UK. If you do not live in the UK, you can still get an Oyster card but only when you arrive in London.

Why do I spit black in the morning?

The discoloration may be temporary, caused by exposure to smoke or dirt in the air, or it could be due to a respiratory infection. Black phlegm could also be caused by a more serious condition, such as lung cancer. A prompt medical evaluation is important.

What color mucus is bad?

Red or pink phlegm can be a more serious warning sign. Red or pink indicates that there is bleeding in the respiratory tract or lungs. Heavy coughing can cause bleeding by breaking the blood vessels in the lungs, leading to red phlegm. However, more serious conditions can also cause red or pink phlegm.
