Now, what could be better for us closeted advertising executives? Leafing through these weighty tomes while listening to classic mid-century mood music. I was also privileged to receive several great CD's of production music. This is what you would have heard while watching promotional/industrial films of the time (you can even hear some of these on TV shows like The Simpsons.) Having horns and a chorus of "bah-bah-bah-bah" playing while reading these books made me incredibly happy.
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.
