Wow! Just when I think we've seen all possible perspectives of this, along comes another - totally unexpected - one. Thanks gecolon (and of course everybody else). You are a person who could sing with conviction the song "Both Sides Now"!

Hi Alto, yes thanks, I do feel considerably better than I did before I lost 70 odd pounds. But I get reminded (and punished) when straying from the strict diet. My foot and ankle swell up, and I have to walk with quite a painful limp!
