Sub NumberingParagraphs()

    Dim iParagraphs As Integer
    iParagraphs = ActiveDocument.Paragraphs.Count
    
    Selection.HomeKey unit:=wdStory
     
    Do While iCount < iParagraphs
        iCount = iCount + 1
        Selection.TypeText iCount & ": "
        Selection.MoveDown unit:=wdParagraph
    Loop

End Sub

My mate, being curious about, but not having experience of, the workings of such things, took a look and got the basic idea, but couldn't get his head around why the number of loops is seemingly instructed to be one less than the number of paragraphs. Surely, he said, it should be "less than or equal to," rather than "less than." Well, no. His kid got it straight away, and came up with a lovely semi-analogy; which I now share, in hopes that others who've been puzzled by this oft-seen seeming-paradox might see the light. Let's literally (yet figuratively) walk through the macro…
