Recently, I was privileged to see a superb short film adaptation of the wonderful Stephen King story, "All that you love will be carried away." The movie, All That You Love, is a work by Director Scott Albanese and is simply amazing. Kent Vaughan, a veteran actor, does an incredible job as Alfie Zimmer, the burnt out traveling salesman with a penchant for bathroom wall drivel. I especially liked the adaptation of the fantasy sequences in the story to the screen.
Scott recently launched a site for his film, All That You Love, that contains background on the movie as well as a great gallery of behind the scenes photos. The movie itself is in the process of being cleared to be shown on the site. I will update you when that happens. In the meantime, please check out the site, it is well worth your time.
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.
