Just as a completely irrelevant but irresistable aside, I have to say that philosophically I completely agree with IO's assertion that the state has no business in dictating individual attitude to risk and that if it did there would be no mountain climbing , scuba diving, climbing etc. Alas the b*stards still compel us to wear seat belts in our cars, crash helmets on our motor bikes, and have drafted anti smoking legislation which could easily have accommodated both smokers and non smokers without being unfair to either. Nanny state will out.
