A. Sadly, at any given time 30% of people are experiencing back pain. More so for people as they get beyond 30 years old or so. Over their lifetime, 80% of adults will experience a back problem. Since only about 4% of people do any significant lifting, any number of things can trigger back pain or injury. You normally think about hurting your back by bending or lifting or twisting wrong. Unfortunately, back problems occur most often over time, through ordinary wear and tear of daily lives. So standing, sitting, driving a lot, working, dancing, reaching and virtually everything else you do can trigger a back problem.
