Here is a great video made by PBS in the USA about the trend of Americans retiring in Mexico, and how inexpensive assisted living centers are here in Mexico. I got it from I GO Yucatan Why Foreigner are Flocking and Retiring to Mexico
I think Mahahual would be a great place for an assisted living facility for retirees from the USA and Canada. You have a great warm climate, cheap labor, and the Mexican Caribbean.
Thanks for reading,
