For several years, tightness in neck and upper back due to tension and high stress, resulting in head aches and just feeling bad. About a 1 1/2 years ago, really started working on ways to relax, mind and body…dusted off the Wing Chun I had learned and found other tutorials for new training, even Tai Chi 24 form. After pounds of Exederine and Tylenol, joint suppilements and an Ulser. Still in a stressful job, but stress free due to centering and focusing on mental peace. Additionally, use to take a couple of sleep aids to fall asleep due to busy mind. I have freed myself from sleep aids and only take 2 vitamin supplements with no prescription medications (I can brag since I am soon to be 63) I thank Sifu Jon for opening his doors, 1 first saw his teachings on Tic Tok and became motivated again. I had never heard the internal energy explained like he does. Awesome and many thanks again @Sifu John Cogan . Search for peace, be patient and peace will find you..
