I know one terrifying thing about old people, I am going to become one soon!
Beware of my philosophy, and gosh darn it, I have one that kept me alive. I am a good coffin dodger!

Now seriously. Old people don't change, just their bodies.
If somebody was an idiot for 70-80 years, don't expect great philosophy for the next few years of life they may have to live.

One thing I learn from elders though, the more you live the more you complain about pains... still death look a lot more worse.
But no one complained while dead.
