I think I may have worked it out. Today Erwell had his regular 3 monthly PSA test. It has gone down from 0.08 to 0.06 during the last three months. Hopefully it has levelled out. We had a wonderful trip to Tibet. Made it to base camp and viewed the magnificent Mt Everest. We were not too troubled by altitude sickness but the air sure is thin at plus 5000 metres. I have retired. I am envying you all your summer but the seasons turn and I love that .
Good wishes.
