Marydean - to answer your question about whether my 'magic weight' has varied with age, I'd say it would have but I don't know what the figure would have been when I was in my 20s because I didn't own a set of scales.

Though I do remember weighing myself at a friend's house when I first arrived in Australia and I was 24 and 54kg. I'm sure if you'd told me then that I would one day be elated to be 'down to 70kg', I would have shrieked in horror LOL. So I'm guessing that back then my 'magic weight' would have been around the 60-65kg mark.

I guess weight is a sensitive topic and I'm not totally sure what the reason was for the OP but to me you're either comfortable answering the question or you're not.

I'm not sure how 'helpful' our answers are because everyone is different and it's really comparing apples with oranges. But if I only posted answers that were 100% helpful then I'd probably post a lot less so idle curiosity is enough of a reason to ask a question IMO. It's really like asking who had a VB or who had a CS - doesn't really tell you a lot because every labour is different. Not that I want to open that can of worms, mind you.
