By early 2009, Nick had been labeled a 'walking time bomb' by his physician — his total cholesterol level was 230; his blood pressure was 180/98. He had been suffering from back pain and leg pain for a few years. Migraines or unbearable headaches were an everyday occurrence. He had no energy and felt the weight of the world upon him. Among other things, he was in the midst of a divorce from a 24-year old marriage.
One day, Nick woke up and just could not walk! His back pain had suddenly gotten worse. The Chief of Staff of Pain Management at UC Davis Medical Center diagnosed him with "extrusions in L4/L5". He suggested steroid epidurals to try loosen things up in his body.
On the way back from the hospital, Nick's 23-year old daughter Giana pulled over to the side of the road, turned the engine off and and refused to drive one inch further until Nick promised to attend a yoga class.
Nick's first yoga class was mind-blowing! He felt so much better. Within 6 months of regular yoga, he lost 50 lbs and got off his medicines. His cholesterol levels dropped to 152. No more migraines. Few headaches. Back and leg pain were greately reduced.
Nick then enrolled in a 250-hour yoga teacher training program even though he didn't really want to become a teacher. However, at the end of the program, he left his 27-year job as Senior Manager in Intel to become a full-time yoga instructor.
