The Intrepid Berkeley Explorer site showcases a whole bunch of international travel videos. They are pretty good quality .wmv files and stream through a popup in IE - firefox didn't seem to want to stream them so they are just downloading. I am currently enjoying the latest one from Japan.
The Intrepid Berkeley Explorer is played by David Mundstock. David Mundstock's personal site (warning: audio) has a ton of great pics and information about his television program.
Why are we so willing to watch these on the web, but when a friend/family wants us to see their travel vids, we don't seem so enthused?
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.
