What image do you have of living on a tiny Greek island, approximately 10 miles by 5? Many first-time visitors bring their own tea-bags and cornflakes. They are surprised to find mini-markets stocking these items and many others familiar to the shelves of their local Tesco or national equivalent.
Another worry is "What if I fall ill?"
Ochi problema.
We have a hospital (where my hernia has been stitched together) and enough dentists and doctors to fill Yellow Pages.
Whatever your ailment you will find a specialist. Just walk in off the street. No appointment necessary. Mind you, your first visit to the doctor can take you aback. The surgery door normally stays open with the next patient in line standing there waiting (and almost certainly listening). Just hope he doesn't understand English.
If the waiting room is particularly busy and you are feeling peckish you could strike lucky with a visit from Pantelis, the multi-lingual peanut seller offering fresh Tony Blair peanuts (they were John Major peanuts when we first arrived here).
