You don't need to worry about embalming, which is only done in the case of open casket funerals. The medical examiner will have already sliced & diced you and certified 100% dead meat by the time you get into the hands of any funeral director. Have you guys ever had the "pleasure" of reading an autopsy report? I will never forget reading my brothers after he died of a heart attack. The report included the weight of his brain, so they must have sawed his skull in half so they could scoop out that brain and plop it on the scale. Report also commented on condition of his genitals & anus -- which fortunately passed their rigorous inspection. I'm not at all sure how examining his junk helped them determine that death was caused by a heart attack.
And if still don't want to risk waking up in a coffin, then get cremated and risk waking up in an incinerator.
