I've been tired lately and get dizzy spells .... so Lorena suggested I sign up for Seguro Popular. She got a list of requirements and I had them all. You need a copy of your Passport, CURP, Visa Perrmanente and most recent electric bill. Find the SP office in the nearest Centro de Salud. They fill out everything and you just sign. They have a Pharmacy, do blood tests and it's all free. Someday we'll find out how the service is.
