I heard today on the news that Ingrid Betancourt is 'alive but in low spirits'. I bet she is after one year in captivity. I would recommend that you read my review of 'News of a kidnapping' to anyone new (it was one of my first). I thought they would have learnt that it doesn't work by now.
If she is in similar conditions then she is living in fear of the guards in constant fear of her life, depending on her relationship with the guards she may only be able to visit the toilet once a day. She does have a companion but I think it must be a very depressing and difficult situation.
