Funerals are for the living, as has been already noted with some eloquence.
As for me, I plan on checkin' out with little to nothing left. That way I can see a countdown of sorts. When the money's gone, somebody better pull the damned plug. I ain't goin' hungry for nobody. 
Seriously, though, Mrs. E and I recently updated our Revocable Living Trust. When that sumbitch becomes Irrevocable, it's time to go casket-shopping for the both of us. 
Best look into everything before you go casket shopping. Man, the things that happen when you are in shock from a sudden death, or even prepared for the inevitable.
Hubby's family has a family mortician, everyone in the family that passes goes to the same business. Most do have prepay plans but that don't stop the businesses from increasing the cost by hook or by cook.
Example, SIL's husband died, he thought he had everything arranged----SIL in shock was told new laws had been passed since her Hubby made his arrangements years ago and now she had to pay extra to have him embalmed. Not true, he was not going to pass into another state. $$$$$$ more for the business and who knows if it was even performed.
Then she was blinded sided with the knowledge the casket he bought was too small for him as he was a large man. She needed to up grade the casket at considerable cost or as she was told they would have to break his bones to get him to fit. $$$$$$$
This old lady ended up paying $5,000 extra and over the cost of a so called prepay funeral. It seems that 30 years ago when he had his arrangements made he had paid for what he wished for in a simple arrangement of flowers a top the bottom of his casket. The cost of flowers he paid for 30 years ago now came down two Daisey's and a bright red ribbon. [ a dozen roses at that time cost $5.00]
Then the Cremations thing, some family's want a private viewing before hand, I have seen some weird crap here. The diseased brought out and laid on a table like they were at a buffet as the main meal, some for some reason had been embalmed, 12 hours before the Crematorium, extra $$$$$$ added to the expenses.
Quick story here, when Dad died we never got a viewing, just that the undertaker called to tell us dads ashes had arrived at the Parlor. With out a thought we all sped hell bent for leather to the Home arriving unannounced. Had to have been a dozen or so of us. We barged in and the granite box with dads ashes was brought out and placed on a table. Hard to believe that Dads forcast for the future that he would end up in a shoe box had come true.
I his only child went over to touch the box and the son of a gun was hot, radiating heat from the fire. I somehow managed to call the others over to feel the warmth and equate it with the passion and love he had for his family.
We humans do very odd things when we say good by to a loved one, we go a bit nuts with the loss and that may keep us sane.
We fill the coffins with pictures and momentous the same as the Egyptian mummy coffins, We in some cases take photo's of the deceased in their coffin, a reverse on baby pictures. When Cremated we have the funeral director place objects the deceased loved in the box with their ashes.
Some by request have a favorite Pet put to sleep and follow them into the great beyond beside them.
The whole point of my posts is that I have lost a couple good friends lately and as we are of the same generation my own mortality comes into question. What the heck will the people I love do to me when I become part of the other world. And more importantly is what the heck will I do the next time a loved one passes before me.
