Daniel, to shortly put it yes there are. But which one place to choose would depend on each person individual needs.
What sort of life: a village, a small town or a city, lakes, mountains, sea, rivers? The only downside I can see is the need to learn new language and that most of the Europe is cold during winter which may put off many people who wish to retire in a warm country (not HOT and very humid).
But as for cost of living ... YES there are places in Europe where you don't have to pay your arm and leg to get some living space, food and medications.
What keeps me in Indonesia is: my wife. My wife's family has got this traditional way of thinking she will take over of family businesses, her social network is here for her not only friends but a huge family circle as well not to count all the business partners and acquaintances . To stay and support her parents and grow their businesses which she will later on pass to our children. In Indonesia she is someone important (that is how she feels) in UK she is no one. If you have by any chance seen movie "cek toko sebelah" then you will know what I am talking about.
