Dr. Who is amazing! I only got about halfway through season five before it was pulled from netflix. A good book I read on time travel is called Time Travel by Ronald Mallett. Parallel universes and time travel has always beem quite intriguing to me. I at times when I skate or bike see a look alike of me or just see the back of another skater and just have this feeling that it is me from another universe or time. Tis more fun to think about than this so called material reality that we have been led to believe.
