I might not exactly be the benchmark for this but for the entirety of preschool and then the first 4 years of primary school I went in for a week and took 2 weeks of what I would now call sick leave. Left me with a heart disease and a real scare for what I should do if I ever have kids to avoid this happening to them.
(Child spent 16 % of the year sick. Across two parents, that is nearly a month of absence in a year.)
