Well, if there's an emergency, the waiting lines are prioritized by the situation, and nothing else, but if you go to the doctor because of fever at five in the afternoon, you should expect some waiting time, in bad cases maybe just aboveI three hours.
I assume this of course vary from place to place, but this is in the cities. In less dense places, the lines are generally way shorter.
Max tax is about 50%, this kicks in when you pass 144k USD income. No tax up until 8,4k USD a year (this is mainly ment for those who goes to school and work a little on the side or in the summer), the tax when earning the average 61k, is 30%.
Your rights to defend yourself is that you can use equal amount of force back. This is also treated with the benefit of the doubt, so some excess is of course not a problem, but if someone pokes you in the chest, and you break all the bones in his body, that's not allowed. If someone breaks into your house, you're not allowed to kill him. You're allowed to arrest him. No weapons are allowed in Norway, except for hunting and other activities like that. That means that in no case will you be allowed to use a weapon against a person. If you have been fishing, and walk around with a hunters knife, and you stay someone who attacked you, you would get punished, though mildly.
Also, the highest prison sentence we have, is 21 years. That's what's called a life sentence. And in practical terms that's 18 Years in real life. But our prison system is a rehabilitating one, and we have among the lowest rates of getting back in prison. And it's not possible to get several life sentences.
Though there is a possibility to keep someone within bars after 18 years, if there are clear evidence that they would not be fit for society after this. This is why we expect Anders Behring Breivik to actually sit his whole life in jail.
