How many kilograms does a person carry with him after death?

The weight of adult ashes is about 2 kg to 8 kg, with an average of 4.8 kg. The average weight of men is 5.4 kg, and that of women is 3.6 kg. According to calculations, the cremated ashes are equivalent to 3.5 to 5% of the original weight, which remains to be studied and demonstrated by scientists. An old man of 100 kg weighs 3.5-5 kg on average after cremation. Of course, some old people were thin before they died. Thin to more than 60 kilograms, his ashes should be more than two or three kilograms after cremation. Originally, bones were big, only meat was thin, and bones could not be thin. The temperature in the cremator is so high that everything except the bones quickly disappears, and all the water and organic matter in the human body are decomposed or evaporated. Despite the high temperature, bones are not easy to burn.
