I have learnt something important to me from his site thanks to Parvati (I think it was Parvati). I can still use cannulas when oxygen is higher than 3, don't know were I picked up the information that once over 3 lpm one had to use a mask, I was misinformed. I might do as others now and up it when doing something strenuous.
One of my daughters and partner coming down for the weekend have been informed that we are to watch England play their football match Friday evening, really looking forward to it (that is the weekend with my daughter not watching football !!)
