"The rooms are described as being neat and tidy. There are no windows."

"The three children who lived in the cellar, 19-year-old Kerstin and her two brothers aged 18 and five, had never seen daylight, and grew up with artificial light."

This is such a horrible story. I hate even to mention it. But this link goes to a story that depicts the underground living quarters Josef Fritzl somehow constructed and maintained and kept hidden for 24 years... as he went about his life as perhaps the most evil father ever.

AND: Could it be that it wasn't so dreadful for the youngest children?

Professor Jay Belsky, an expert in the field of child development and family studies at Birkbeck College, University of London, says the fact that the children were with their mother - a source of security - and with each other, could have mitigated the amount of trauma they suffered.

"Potentially, the children could have led tolerably rich social lives - there were four people there, at least three of them for a long period of time. This isn't a story about a child being locked in a closet all by himself," he told the BBC News website.

He said that in terms of the five-year-old, he would have been unlikely to have known what he was missing.

"As a youngster, your immediate environment is your whole world," he says.

"If there were books, games and a TV, there were things for all the children to make a psychological life around. It need not be as atrocious as it might first appear," he says.

That reminds me of Dr. Strangelove's description of life underground. But at this point, one hopes the professor is right.
