There might have been a secret reason Albert Einstein could make a decision

as scary as the one he made in 1939, when he went against his personal

pacifist convictions and encouraged President Franklin Roosevelt to pursue

the research necessary to make an atomic bomb. "I was well aware of the

dreadful danger for all mankind, if these experiments would succeed,"

Einstein later wrote.


A strange life hack might have contributed to his coolheaded attitude toward

the bomb: Einstein is said to have slept for 10 hours a night.
