Billy Schulz is "an old, old man" - he says

We've blogged about Billy Schulz (Grown Man Now) before, and just wanted to let you know that Billy is celebrating a birthday.  His brother Tom has made him a video tribute that goes beyond the usual collage, and Billy gives some clues to his age this birthday.

You can also follow Billy, his mother Dr Jane Schulz and Grown Man Now thoughts and happenings on Facebook.
