I have a friend who sells high-end used cars in the North Dallas/Addison area. Since these are premium cars, they often have to be warehoused indoors which means that there is not a lot of space to walk around since he may have 50 or more cars at a time in inventory. Also, his staff often needs to be crawling around in tight spaces since many of the sports cars are smaller in size. They also sometimes have to pick up, or drop off, cars that are quite a distance away from his location to benefit his higher-end customer. They are more demanding than the average customer, so he and his team go out of their way to keep the customer happy. All of this can lead to problems with the back and neck as the long drives, long hours, and crawling around in tight spaces can hurt the spine.
Since he is one of the few Dallas pre-owned Porsche dealers, he also has to be ready to deal with people all day long. He has to pop out of his chair quickly to prevent any behind-the-scenes problems from affecting the customers. He then has to deal with evaluating new inventory, check to make sure parts are repaired or replaced properly and much more. Then he actually has to manage the business which requires long hours at the computer.
Luckily one of his family members is a chiropractor who has recommended stretching and other exercises to keep the neck and lower back loose. While he may not end up doing yoga or Zumba, he at least is doing some basic physical exercise to strengthen the core muscles and other exercises to stay loose. Doing so should help him with his job so that he can stay focused and out of acute pain related to his daily on-the-job tasks.
