This document describes how a restless mind can prevent sleep and proposes using a treadmill to tire both the body and mind. It suggests walking on a treadmill while engaging in other activities like talking to friends, reading emails, and playing games on an iPad mounted nearby. This allows productive multitasking while exercising and tires both mind and body. By the time all tasks are completed, the mind has achieved peace and the body is ready for restful sleep. An optional bike attachment is also mentioned for those who don't like walking. The overall message is that physical activity combined with mental stimulation can help achieve better sleep.
