I did a Google search of the most expensive and the search result that was returned had one interesting item, which was edible gold. For real, I never knew they was such a term as that.
It is expensive when talking about food but still, theres a lot more expensive commodities like luxurious cars, popular brand items and a lot more. I wonder if gold is not harmful to human body since it requires intense amount of heat to melt it and i doubt human body and digestive system have that amount of heat to digest this edible gold?
