A few months ago, I was thinking about the possibility of cryonic suspension as part of the Australian health-care system.

That's a thought. I must confess I hadn't considered my country to be particularly likely to be a world leader in cryonics adoption.

Unfortunately, I think the pattern theory of identity (according to which your copy is still you) is an illusion, and that this is all cryonics is likely to provide - a way to make copies of the frozen originals.

That belief must be a frustrating belief. Right or wrong I must say my anticipated experience is a whole lot better. But then... I philosophically evaluate preferences over the entire state of the universe by default and yes, 'identity' and affiliation with this form are not something that particularly comes up.
