One of the people in the interview is a medical student who does dialysis at night, and it negatively affects his studies and health.
I am a dual US|EU (Croatian) citizen. I also have lived with type 1 diabetes (autoimmune and insulin-dependent) for almost 30 years now. While I have been fortunate that my kidneys have been fine, if I were to need a kidney transplant, I would absolutely live in Croatia long-term (where I live currently) if I needed a donor kidney.
Croatia has an opt-out system, like Portugal.
Croatia has one of the highest kidney transplant rates in the developed world, and in Europe it competes with Spain and Portugal. You really do not have to wait that long for a kidney transplant in Croatia compared to other developed countries. Here is a good writeup on the Croatian transplant system and how it works: https://cdn.intechopen.com/pdfs/27728/InTech-Action_taken_to...
Anyway, all the best everything stays safe.
Here in Germany I stand in the minority where donation is opt-in, the result being that better not need an organ transplant over here, as it has one of the lowest contribution rates across Europe.
