I'm leaving it up to those I leave behind, how I'm handled after I am dead reflects more upon those who do the handling than on dead me.
But my preference in general is "green" burial - none of these crazy-expensive caskets and plots and toxic chemicals, none of this massive wasting of fuel/energy and pollution of the air to incinerate my remains without even using the heat to warm a cold house in winter (I still am dumb-founded at the wastefulness of cremations). The only use I see to a cremation is to allow a distraught loved-one the possibility of carrying those remains with him/her from place to place until he/she is ready to leave them behind. Ashes are certainly more portable and less 'perishable than a dead body
Social norms and health recommend the respectful entombment of remains as opposed to leaving them out for the beasts, etc. So, if the water-table allows, let them dig a good hole and lay me there to rest and resubmit 'my' nutrients to the earth from which they came (without burning off the majority that was useful or pumping me with preservatives). If the water table is too high, some rocks in the gut and a suitably deep river/lake,etc. will also suffice. If a box is required, fine.
If someone feels piously inspired to entomb some artifact along with the body, God bless him/her for the sentiment. I am skeptical as to whether the item will be of use or importance to me in the hereafter, but perhaps it will be important should a later person discover the remains, giving them greater context by which to understand and interpret the discovery. For example, my wife worked at an archeological dig in Ireland where they found a body buried with quite an expensive (for the time) assortment of items, and in the midst of an area known to have been quite poor at the time of the man's burial. Other graves evinced no such plethora of items, so why this man? From the artifacts located with the body, taken in context with those found in the surrounding village, they deduced that the man had been quite rich, but in
friends rather than wealth - various citizens of the village had placed items from their own homes/jobs into this man's grave, according to the theory. Why? Perhaps to show respect or honor... :thumbup:
