Just seen this thread and must say how touched I am by your concern, folks. Also sorry that I have caused you to worry by my unexplained absence from the forum. After my cancer diagnosis I decided to get myself as physically fit as possible, to help me deal with whatever the lymphoma might throw my way. I joined a running club and also do regular boot camp sessions plus various gym classes. So far, so good - I saw the Consultant Haematologist today and she is very happy with my blood levels. Extreme tiredness is the only side-effect at the moment. Thanks again, everyone! Richard
