You might discuss the law, and we do in Germany. There's a rough cut-off at 50%. Below 50%, there is nothing, and being above 50% doesn't get you more. This was decided in the past. There has been thinking about it, but it's still the law. It's still in force at to this date.
This creates some problems. If you have 40% and you are a psychologically traumatized person, what do you have to look forward to? You're looking forward to 50%. This gives a bit of a problem in curing or healing the disease. This is what we talk about a lot with our jurists and psychiatrists, but for the time being, it's like that.
