Rest your right hand on a door handle (or the like) and rub the top and sides of one foot 25 times with the other foot. At the same time rub with the left hand the back of your neck as far as you can reach starting down the middle of the back, then all round the neck, and then throat. Then switch to using the opposite hand and foot. In total, this should last 8 full breaths.
