inconsistent life expectancy (used to calculate YLL)

[EvaJanouskova]

HealthBurden.docx write-up says:
"Modelling Years of Live Lost (YLL)
At the point when an individual in the model dies, the time, the age at death and the cause of death is recorded. If that death occurs before their 70th birthday, a day of ‘lost life’ is recorded as being attributed to the cause of their death each day until the day that would have been the 70th birthday of the deceased. The choice of 70th birthday is arbitrary and represents the point before which a death may be considered as ‘premature’."

But in the healthburden.py is:

        p['Age_Limit_For_YLL'] = 90.0  # Frontier life expectancy at birth
