Lost returned to channel 4 tonight, with the first 2 episodes of the second series. We finally found out what was down the hatch, and what happened to the people on the raft.

I don't know what caused it but I first noticed it when I stood up to get off the train this morning. My back gave out a little twinge of pain. It got worse during the morning, but would only hurt when I first stand up. Once I've been standing up for a while, the pain goes away. When it was time for my morning cuppa, it meant I hobbled to the kitchen but could walk back normally.
