Do you have job where you have to lift heavy objects like cement bags?

If so, for the sake of your spine, you should follow this link, popularmechanics.com/technology/upgrade/... The first time I posted this, I got a Violation Notice!
Update: In their tech category, /upgrade/4213268.html
Update 2: I'm posting this to help people, no other reason. The heaviest thing I lift is a pot with veggies in it! I don't like A's with racial slurs, either.
