Thanks very much for all the kind comments, they are much appreciated.
Dave - I don't have a set number of hours that I work on my models, some days I will sit at my bench and not leave until 10 - 12 hours later, other days it is only one or two hours at a time or some days none at all. I am retired so time is all mine, and I am extremely lucky to have a very supportive wife who also takes a keen interest in my hobby. But I believe the main driving force for me is the love of modeling, especially WW1 aircraft, I can model all day and never tire of it, even when the going gets tough I still thoroughly enjoy the hobby. As long as my eye sight is good and my hands are steady I will continue modeling, I have a great deal of fun building my models, once the fun factor disappears that will be the day I give up modeling.
