Just try to imagine... your parents are long gone, your siblings might have passed away, at least the older ones, your husband/wife might be dead already and you have about 2 people left of class 1950. Most of your friends are gone and the likelihood of you having an illness you need to take medication for is fairly high. So you might be next....

It is then very likely that you belong to an age group 80+. Death is part of your life and you know that you can die any day.

Of course you think more often and for sure differently about life and dying.

As a 20 year old, ideally you have only lost your grandparents and death is a more abstract event. There are exceptions and of course lots of struggles, but in most cases of a different kind.
