For anybody dependent on private insurance where "pre-existing conditions" are seen as disqualifying people from getting what they nave been paying for through premiums, it seems likely that things are liable to get pretty hairy.

Improved understanding of the human genome is likely to demonstrate that an enormous range of conditions needing urgent medical help are in a sense "pre-existing conditions".

Of course that could undermine the whole racket, since what's the point of paying for insurance that isn't going to come through when needed?
