Have you ever been in a meeting where you are getting tired and cannot concentrate? When running seminars I introduce Brain Gym - a technique commonly used in schools to help rebalance and energise thinking and kinesthetic, auditory and visual ability.
Try this in your next meeting;
Stand us and firmly plant your feet a little apart and look over your shoulder as far as you can and fix on the items you can see. Then twist back around the the front and rub your ear-lobes (stay with me on this), turning your ears inside out all along the edges of each ear and then run your lobes again. The repeat the twist around to look behind you and you should see your ability to see further improve. This is to do with the rebalancing of your brain. It is quite amazing; A less embarassing way to do this is to quietly rub your ears I have also been stuck in a wheelchair for 3 months having snapped my Achilles Tendon at a Scottish library conference and this is an exercise that will concentrate on that pesky part of the body - it helps activate the front/back brain, increases verbal ability and increases creativity. Sitting with one ankle resting on the opposite knee, place your fingertips at the beginning and end of calf muscle area. Search for tight spots at the beginning and end of these, and gently hold them apart until they relax. While holding these spots apart,slowly point and flex foot, extending it further up and down as this gets easier
