Although the vast majority of falls do not result in injury, there is the potential for injury and in some rare cases death. The key is to strike a balance between preventing falls and maintaining as much independence as possible. Have adequate lighting by stairs. Ensure that you can easily reach a light from your bed if you get up at night. Install and use hand rails in the bath tub and by stairs.
Some medications can lead to drowsiness.
This can contribute to a fall. Certain drugs, when taken in combination with other drugs, result in unwanted side effects such as blurred vision or dizziness which can also contribute to a fall. Keep your muscles in shape. There is no age at which exercise is useless. With strength in your arms and legs you will be in better shape to brace yourself or catch yourself if you fall.
