Essential knowledge

A fascinating read.  Despite the howling gale outside, I now understand cognitive bias, epigenetics and the huge variations in estimates of the value of human lives. On the latter, I discovered that a 79kg person contains elements worth $118,000 - including carbon worth $54,200, Potassium - $6100 and Arsenic $0.12. 

The plan now is to cook a mixed vegetable curry with dal tadka.
