Many things have changed once one is 85 years old (I guess). As a matter of fact there seem to be more things changed than unchanged – even on a behavioral and personal level as behavioral psychologists tell us.
The same is true for physical conditions such as Blood Pressure (BP). In a recent study systolic hypertension (that’s the first figure) was not associated with higher mortality in over 85-year-olds. This has been checked out by the incredulous Dutch and more than 500 85-year-old residents in the Netherlands were followed up until the age of 90.
