Results of a study published today show that experiencing the hostile divorce of their parents may have a long lasting impact on their immune system.

The study, by Carnegie Mellon University, made a clear finding that it is not parental divorce itself that is a predictor of future poor health, but a hostile, or 'silent' divorce ie one in which the parents were no longer on speaking terms.

I'm not sure this can come as much of a surprise to those who practise in the family law field: experiencing parental divorce is tough enough for any child, but the stress of witnessing years of conflict between the two people that child loves most, is always going to be harrowing. It does seem pretty shocking to see that the impact on health can last as long as 40 years though.

Yet another reason for fault-based divorce to be abandoned once and for all in this country?
