Hello!
• You could fall down stairs if something's blocking your vision, such as a blindfold. (You wouldn't be able to see the steps)
• If the steps are too far apart, it might be hard to get down . This could result in someone falling downstairs.
• If a person pushes another person who's standing at the top of a flight of stairs, they could fall down and severely injure themselves.
• If someone's dancing, running, carrying too much stuff, or is distracted by something like their phone, that's another way they could fall off.
