Good points. I just post the above information for the benefit of those that may not have been exposed to it. It may or may not be good information, that being for each individual to decide. The state of the art is no doubt changing regularly. New things coming along all the time. It is good we have the input and ideas from a number of people and variety of viewpoints. It is for discussion only. Definitely not medical advice. John
