21 gramms is the weight of a humming bird,a chocolate bar or five nickels.but some say this is the weight a person looses at the time of their death,could this be the soul leaving the physical body,
it is an interesting thought,but my personal views dont accept this as possible..
from death onwards you internal body tissues,enzymes etc start to break down,the pace of which this happens depends on the individual,gasses and fluid are lost too..
lets say a person dies with an injury..the loss of a limb,muscle,tissue,body fluids are all going to present with the loss of mass weight..
its like the old fashioned belief that an adult body has approx 8 pints of blood within it..utter rubbish..for those who believe this,can you really see a 22 stone man having the same amount of blood as a 8 stone man..im sorry but the larger man would be dead..you have roughly one pint of blood to each stone you weigh.
i cant see how a person whom is weighed before and after death wont see at times some reduction..but i certainly wont agree its the soul of the person whom has left..and even worse secenarios if you weigh them after a post mortem..
