Whats the point

Wikipedia's no help:
"The time to carry out a cremation can vary from 70 minutes to approximately 200 minutes. Cremators used to run on timers (some still do) and one would have to determine the weight of the body therefore calculating how long the body has to be cremated for and set the timers accordingly. Other types of cremators merely have a start and a stop function for the cremation, displayed on the user interface. The end of the cremation must be judged by the operator who in turn stops the cremation process."

apparently if they are that fat they burn forever as they are a bit like a candle....
