Why is it OK for people to become flippant when they hear that an old person is near death?
Tell someone a parent is ill. Usually the first question is "why?', but the second is invariably "How old are they?" If a person is at or past a predetermined age, there is a big sigh. Perhaps a nod, or a shrug. The context, the hidden message is "It's OK that they're dying! They're OLD!"
No doubt, there are older people that have just worn their bodies out. They are done. Some look forward to the release death will provide.
BUT FOR GOD'S SAKE, NOT ALL OLD PEOPLE DESERVE TO DIE!
If these hollow, sad people with that belief were honest, they'd probably blubber about "quality of life" or "a burden on their family" or some such nonsense. Whatever your personal belief, some people are fighters. They have life left in them. It may not be the life you would prefer, but then again, it is not YOUR life. Just assuming that a human being has a shelf life like a can of beans is asinine and inhuman.
Next time someone tells you that a grandparent, parent or other older relative is ill, check yourself. Don't be an ass. The soul you save may be your own.
