Health care systems around the world vary greatly, from fully-funded public systems to private insurance-based models. In countries like the UK and Canada, citizens enjoy universal health care coverage, making access to medical services affordable and accessible to all. On the other hand, the US relies heavily on private insurance, often resulting in high costs for individuals. Some nations, like Australia and Germany, have a mixed system combining both public and private sectors. It's fascinating to see how different countries tackle the challenge of providing health care to their populations.
