The easiest answer to this question is anyone and everyone. No one on this planet is immune to back pain and it is something that you will probably end up experiencing in your lifetime. As you get older, though, the risk is going to be even greater (more specifically in the 40 to 80 age range). What is interesting, though, is according to Medline, it is estimated that 8 to 10 people will endure low back pain at least once in their lifespan. You do the math; that is an 80 percent likelihood that you will suffer from low back pain at least once.
