Thanks d-man that was a very good point and one I hadn't considered. It makes a lot of sense.

Prospect your words of wisdom were also very much appreciated. Your quotes about wasting time were excellent. I am getting to an age where time is my most important possession and its rapidly decreasing. I was just curious about timeframes and I made up my mind long ago that I'll be here as long as it takes and if it takes too long I guess it'll be my children who'll benefit.
