Thanks to Bob and Steve for their comments to get this article where it is. Quite happy about it except for two things
Picture of Ira Progoff has bee distorted on page 4 in the pdf - its fine in the Word Document and should remain like that!
I exaggerated my youth on page 8 - instead of 18 I should say "in my twenties" (or 22 in fact in 1971)
Hope this helps
