When you need on-the-spot smarts, put your index finger on the Renzhong (the acupressure point in the middle of your philtrum, which is the spot between your nose and upper lip). Press in for 30 seconds. Experts in Traditional Chinese Medicine suggest using this technique to increase alertness, clarity and focus. They believe that putting pressure on this point accesses nerves which carry signals to the brain. We know that it works for us!
