We’re both mid 50’s, came here looking for a lifestyle change and absolutely LOVE it. I agree and endorse everything Rascalmate has said.
We both work - but because we want to ... my wife is a Naturopath / Yoga teacher and loves healing people (the climate is especially conducive to yoga!!) and I work part-time because I wasn’t ready to become inactive just yet ..... but the pace of life and the people make working an absolute pleasure. It is with no hesitation I can say that the Spanish we have met have been the loveliest, warmest, friendliest most welcoming people we have ever encountered.
Spain is a completely different way of life than to that you are used to I’d suggest. As Rascalmate says, moving here will add 5 years to your life - if not more.
