When I was a kid, one of my favorite vacations was to Greenfield Village in Dearborn, Michigan. Henry Ford had recreated the original Menlo Park Laboratory and I wanted to see it. For a ten year old science geek, this was second only to the Smithsonian on my list.
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.
