Experiment 1 (Taking the iPod for a Walk 2)
Get up out of a chair your usual way.
Then sit down and this time, look at something in the room while you're sitting there, such as the TV, a spot on the opposite wall, your feet - anything. Then get up out of the chair while still looking at this object. Don't take your attention from the object the whole time, at any moment.
Notice anything different in the getting up?
