How to overcome the suffering of attachement to the body's continued existence (in Western modernity)?

An important part of the Path is overcoming the suffering of attachement to the body's continued existence. I don't know if that's desire for living or aversion to death - maybe a combination. Therefore, I'm wodering if someone can share their experiences on this very essential aspect of the practice - preparing to die. In the Buddhas teachings we are adviced to watch the after death-process; dead bodies on a charnel ground. But this is very difficult in modern (Western) society. I managed to get three days in meditation with a dead friend (no more is allowed in my country). They'd put some cotton in his orifices and some lubricant on the body. He looked like wax and I felt like I were at Madame Tussaud or watching Lenin. My friend didn't rot or stink so it was no good really, because the whole point is meditation on the process. I've tought about trying some hospices and morgues. Surely they'd kick me out, but I also think it might be disrespectful; they're grieving and probably not Buddhists! Everything would be better with a charnel ground. What are your ways of preparing for death? If you are living in a county where death is a taboo, you probably have met some of the same challenges as me.
