Following high school, Claimant worked less than two years at a Chinese restaurant in Chesterfield, Missouri, and with Conoco Pipeline, performing general labor work. In approximately 1990, Claimant went to work for his father's construction business, Gary Clift Construction. He worked for approximately two years with that employer as a foreman. This job required Claimant to lift and carry up to 100 pounds and use saws, hammers, and other construction tools.
After leaving the construction business, Claimant established a career in the automobile sales industry. He worked for a variety of dealerships selling cars and in customer service. It was during this time that Claimant suffered an injury to his right knee, necessitating an arthroscopic procedure. After receiving treatment for his right knee injury, he experienced only mild, intermittent soreness about once every six weeks. Claimant was adamant, however, that the right knee symptoms never interfered with his job activities.
In approximately 2000, Claimant suffered a laceration to his right hand while pushing a shopping cart in a Wal-Mart. As a complication of that injury, he developed reflex sympathetic dystrophy in his right upper extremity. Claimant underwent a series of stellate ganglion blocks at Barnes-Jewish Hospital and eventually underwent a right dorsal sympathectomy on February 1, 2000, also performed at BarnesJewish Hospital. Claimant missed approximately one week of work following the right hand injury. He had some residual problems, including an inability to sweat on the right side of his body. His right hand also gets cold when he is outside during cold temperatures, and he sweats excessively on his left side because of his inability to sweat on his right side. Again, however, Claimant fiercely denied that this condition ever impacted any employment that he had throughout the years, and doubted it would have prevented him from performing any job tasks.
From 2002 through 2006, Claimant returned to work for his father as a general carpentry foreman at Gary Clift Construction Company. Claimant said the prior hand injury and resulting condition never prevented him from performing any job tasks.
In 2009, while working for Kingdom Kia as a salesman and floor manager, Claimant suffered a heart attack. He under
