All their elderly politicians there dementia, terrible?

Not every old person will become demented but it is a common enough disease anywhere in the world.

We all sexperience different medical issues in old age...some of these might be the same, but some would be different.  For eg, some peepur may have diabetes, while others have high blood pressure.  Some may have Alzheimer's while others have Parkinson's.  Some have a stroke, become wheelchair-bound or worse, bedbound, others lose their vision completely due to glaucoma..

生老病死.

The 3rd character which comes before the 4th and last is scary.  Nobody wants to go through that but nobody can escape that, save for those who die of sudden death or who end their life prematurely.
