You know a lot, but we're trying to get a few more ideas into your head.
Test Subject has nailed this problem, Flenser hit on valid points as well.
I will be the first to state that you are responsible for your own health. If you want to trash it, then go right ahead and expect no one to save you.
It seems to me Medicare is going to have to make massive cuts in the future as it simply unsustainable. Social Security can be somewhat sustained, but the point is to keep food on the table and a roof over your head, that's it for SS.
The tax burden of these seniors healthcare is going to be astronomical, we can't pay this, we shouldn't be expected to pay it either. So I would advise any senior to take very good care of themselves and study up on suicide methods when the pain is too much to take.
There's nothing wrong with dying. Nothing pissed me off more than when we ran codes on elderly that were long past their prime and brought them back so we could milk the system for 2 months with them on a vent.
The aversion people have towards death is largely out of humans separating themselves from nature. They look at nature and think it was ugly and scary and they don't realize we're all just carbon based life forms, from the snake on the ground to we the higher primates. Death is gonna happen no matter what, so get out there and live your life and stop holding onto this idea of living a long life. Death at 55 isn't unreasonable, that's plenty of time to see the world, learn a few things and pass away.
