Tree climbing and other things

The Gorse Fox has spent most of the day in his study.

Part of this was climbing around the branches of the family tree - rather unsuccessfully - but at great length. The rest was triggered by the arrival of the post and a new missive from Starfleet regarding the changes to his pension now that he reached pension age. This latter missive proved to be confusing. It seems that his Starfleet pension will go down by X now that his state pension will contribute Y - but the Starfleet pension will also go up by Z. Oh, and by the way the State pension isn't taxed directly - that is taxed via the Starfleet pension. Can the Gorse Fox work out his budget based on these? Not on your nelly. He'll just have to wait until the next payments are made and see what happens.
