German insurance companies and some statistical collection folks....got together and developed a number that they feel is reliable, over the number of Germans (remember, 80 million) who have chronic pain. They believe 13 million Germans have chronic pain on a regular basis. Roughly one out of every eight.
Over the past couple of years, there's been a new trend developing in Germany....where a specialized fitness studio opens up, and it's strictly run by doctors with a background in muscles and pains. One is about to open up in the next village over from my town.
A gimmick? Well....some people probably do need to stretch their backs more and develop some ways to relax themselves.
How many of the thirteen million are just mental issues and blaming their back or knees? It's hard to say. A lot of older Germans will complain about knee issues or hip problems, and want the doctor to fix what nature and hard work has given them. Some are looking for the magic pill.
If you sat down and chatted with a dozen Germans....you'd likely find at least one or two who complain about some chronic pain. So don't be surprised if Huns one afternoon happens to bring up his chronic shoulder pain, and spend thirty minutes chatting about it's intensity.
