I´m thankful I live in a country with one of the best worldwide public health services (Spain) besides our politicians are trying to benefit the private health.
Private health is not only more expensive but also less effective. Medical insurances companies always try to apply the cheaper treatments and the renovation becomes extremely expensive if you need a long time treatment.
