All kidding aside, the Goodwill gets a lot of high quality cool stuff donated to it. Stuff that can make it some serious money. I know a lot of you probably would think twice about going to a thrift store. Now you can get a peek at the spiffier junk without the smell of old clothes.
Shop Goodwill is an auction site for some of their more esoteric donations.
I have found it helpful to do the stretching exercises my physical therapist recommends. Do some core strengthening exercises, such as the ones highlighted at The Mayo Clinic. By keeping your core strong, your back won't put itself in a position to cause that sciatica pain you are having.
