If I'm right, I think there are about five insurances.
There is the health insurance. There is the nursing insurance, which is for when you are, for example, no longer able to do anything by yourself, when you need help from a nurse to be washed and so on. Then we have to pay the unemployment insurance. We have to pay into the pension plan. These are the four.
Then, although I would not call it an insurance, every German pays into the unification some percent of his.... It's called the solidarity money. It's like an insurance.
