It was a traditional ceremony for signing an agreement with Finland in 1983. The Finnish foreign minister and Maharajakrishna Rasgotra, foreign secretary, sat down to sign, with their prime ministers standing behind them. Afterwards, PM Indira Gandhi told the latter, “foreign secretary, you are losing hair!”
Three decades later, Rasgotra, at age 90, began writing his book, A Life in Diplomacy, and finished the task within ten months. His strong memory has stayed on, if not the hair, though, as a matter of fact, he still has more hair than some of his successors born around the time when he became a diplomat!
