Nobel prize candidates wait often over 20 years to win their prize

The study found that average waiting times for Nobel prizes are increasing exponentially, with average age at which laureates receive the award also rising. This trend threatens to undermine the prestigious award, as the predicted average age among prizewinners could even exceed life expectancy by the end of this century.
