This data is then frequently compared to the incomplete and inaccurate data from before the initiative and can result in considerable disparity between the statistical result and the expected effect. That frequently masks the close correspondence between the expected and actual effects. So you start with data that's apparently good enough to act as a "good empirical reason for a public health or safety initiative", but it turns out it's so bad it will allow a doubling of the wearing rate in a very short space of time to make no impact on serious head injury rates when you look at the data afterwards? And it turns out it's magically just as bad everywhere you look at the population level, reproducibly so. And it also turns out when you haven't had such a law and consequently a big change in the data collection methods, and have a good hard look at the statistical record in light of naturally evolving wearing rates, that there appears to be no effect on serious head injuries at the population level as wearing rates change naturally. And it turns out where disparate groups (for example, UK juvenile males and females) have different wearing cultures, their serious injury rates aren't appreciably differentiated. Pete. Haven't you got work to do Clinch? I hope that you're not skiving and browsing and answering the newsgroup on public funds. -- "Primary position" the middle of a traffic lane.

Mr Crispin: You are asking the wrong question - it is too difficult for me. Child: It is a simple question. Mr Crispin: No - sorry - you are asking the wrong person - ask your mother when you get home. Complete fabrication of a reply to hypothetical straw man question. So what would you answer to a child who asked that question? This seems a very reasonable question to be asked of someone charged with the education of our children. -- "Primary position" the middle of a traffic lane.

He was thrown into the passenger seat and lived, had he worn a seat belt he would have been killed. -- Simon Mason http://www.simonmason.karoo.net/ |

"Judith Smith" wrote in message Well, I've drunk 100-120 units a week for 30 years, so I must be due to die very soon! How do you make up this 100/120 units a week - if you don't mind me asking? It would be nearer 100 units in a normal week. In an evening, I might have 5 x 440 ml cans of 1.9 units and 2 x 440 ml cans of 2.1 units which is 13.7 units. I then go to bed at 9-00 pm to get up at 5-30 am. I don't get dehydrated as the stuff is 96% water anyway. In a week, that is nearly 96 units. If I am not at work the next day, I may have a couple more which would take the total over 100 units. -- Simon Masonhttp://www.simonmason.karoo.net/ You are Glug2 AICMFP |

It's a bit difficult to address the 'points' you raise if they are mere endless and irrelevant vacuous twaddle. Socrates had his Plato to expand on every question he raised. What did I do to deserve you? You continue to show little knowledge of the currently available literature on the subject, or indeed much indication that you have even been bothered to try and keep abreast of it. Consequently your opinions, even though you tend to see them too much as facts, are actually far less informed than you appear to think. If you don't want me posting to point out your opinions have holes in them it would be best to close up the holes, rather than pretend they're not there.
