I am shocked at your outburst, I could only read your first message you know nothing about me and what illnesses I have had in my life, you are not the only one who has had cancer. I am sincerely very sorry for you, I know how tough this is.  Maybe we do not share the same sense of humour. As I see it, Alex just asked a question in a tone some did not like, unless I have read your message wrong and if so, I very sorry. How do you know that this was for research? I am very sorry you have been through such hard times. I refuse to be drawn into further discussion on this with $. Alex I still feel you have asked nothing wrong and people are often too afraid to speak up on this board and things taken are out of text. I still stand by my words being I feel it was a very fair question and cannot see what the fuss was about and shall not post again. Sorry Alex
