Well, 12 years worth of _authorized_ absence (so maybe like 3,5 months in total) _on average_. I know of people, who maybe had a few days of absence in total over the 12 years of schooling. I know of people, who missed more than a year in total and they are doing very, very well in general professionally even when their health isn't so great.
