Vary your daily activities (Tip 17)

[pioneer]

Plan your work so that you are not doing the same thing for extended periods of time (such as performing the same activity or using the same part of your body). Also use different input devices, such as your mouse and keyboard, to accomplish the same task. For example, to perform a scrolling task, you can use the wheel on the mouse and the arrow keys on the keyboard. (ririanproject.com)
