In some areas people are going to be buried in twos to save space. It's strange but I've never fancied cremation for myself but see the sense in this proposal.
It seems pretty obvious that the intention is primarily for loved ones to be buried together, but I immediately began wondering who it might be nice to be buried with, other than my other half.
In terms of being buried with a hero my current one is the writer Patrick Hamilton. Otherwise, I would just go for bust and like to go for a world record and be buried with about 650 politicians, the contents of the House of Commons. That would merit a posthumous honour for services to the country.
