I like the idea of rotting quietly in the earth, hopefully nourishing the soil to the benefit of the plants and insects around.

Friends of mine whose son died from cystic fibrosis buried his body in their garden, but had to purchase a small amount of land from the farmer who owned the field their garden backed onto in order to comply with regulations about distance from various things (not sure what), but I don't know if the law re this is different in England.
