There are a variety is issues which could give rise to avoid retiring overseas. Of those reasons, herein are my “top 3” worst reasons to retire overseas:
HEALTHCARE
While some jurisdictions may, in fact, have superior healthcare facilities to those in the United States, the healthcare services of many countries are far inferior to those in America. Consistent access to quality medication at affordable rates can, surprisingly, be more challenging than you may realize. Also, when you are of retirement age and experience a serious medical challenge, it can be extremely expense, if not life threatening, to travel (or be transported) to a neighboring country which has qualified physicians needed to properly treat your ailment. While you may do your best to choose a favorable jurisdiction for your golden age, countries which boast low-cost retirement havens often lack proper medical facilities.
FAMILY AND FRIENDS
Assuming you have children, you may find yourself missing out on watching your grandson’s first baseball game or granddaughter’s communion. Lifelong friends, who are also of retirement age, may not have the resources to come and visit you but once every few years. Unless you are part of a small community to provide you with the emotional support needed to maintain a healthy emotional state of mind, it is easy to become increasingly depressed living isolated from family and friends. Are you mentally and emotionally prepared to communicate with your closest of friends and family via video or social media? When you no longer wish to travel back to the United States, there may be extended periods of time when no comes to visit you either.
FINANCES AND EXCHANGE RATES
Lack of finances ranks among the primary causes of tremendous stress. Unless you have reasonably substantial savings for your retirement, you may find yourself in an extremely uncomfortable position overseas. Adding insult to injury, if you wished to work part-time to generate some additional income, most retirement visa’s do not allow for any formal work to be undertaken by a retiree as it places unnecessary burdens on the local community whom often struggle with finding work for their families. Additionally, currencies and exchange rate are subject to slow degradations as well as massive swings. Meaning, you may have moved to a country wherein you enjoyed a favorable exchange rate when you arrived but find yourself getting far less ‘bang for your buck’ as time moves on.
In general, the crime rate against Americans and other expats in Chapala and Ajijic is fairly low. The crime rate seems to ebb and flow depending on the prosperity of the times. There would be crimes like break and entry and sometimes it's because people haven't been careful, prudent, and cautious like locking their doors and windows. 
The currency being used by Portugal is the euro. If you have dollars and you are coming for a vacation from the US into Portugal, or if you have pounds from the UK or Swedish krona from Sweden, you could buy euros at your local bank. It is also possible to buy traveler’s checks although I don’t see a lot of people using traveler’s checks these days any more, but they come with a guarantee and protection, so a traveler’s check is a more suitable choice...
On a personal level, with three little kids, I am pretty family-oriented and I have my business. I work day and night. .jpeg)
Restaurant cost in San Juan del Sur, Nicaragua all depends are where and what you want to eat. The cost will vary from as low as US $2 to as much as $20-$30.

Rice and beans is the Nicaraguan choice of a good meal and you can get a good side dish of this prepared Nicaraguan style.
All the doctors that we know in Panama were trained in Johns Hopkins, Tulane University, and Georgetown and they come back here to Panama to practice. 
Editor’s note: We had the privilege in early March, 2017 to talk with Michael Eager. The Eager family is a bit of an institution in the Ajijic area, where Michael’s brother Mark owns a real estate sales company and Michael runs the business that started it all in the 1970s, formerly the Posada, and now the Nueva Posada. In this interview, Michael tells us the unlikely set of events that started it all when Ajijic was just a small, out of the way village and well...
