Back Pain Information

I noticed on Twitter quite a few people in their 30s feeling old because they were having back pain.  I did some research and found in one study 50% of 18-20 year olds had already had some back pain!  I learned a few other interesting tidbits too, so put together this information.   If you or someone you care about has back pain, you should check out my Kickstarter project, Back Up!
