The barber that cuts my hair is an old school bodybuilder and his elbows are very pointy too. I have no idea what that is about...he looks awesome for someone over 60. He looks better than I do...
I have had lower back pain for the better part of the last 24 years (until I figure out the true cause) and I have spent over 10,000 hours being treated, exercising, or reading about lower back pain...
