In the fifties and sixties F1 drivers used to race much more than the "modern F1 drivers "  and in different racing categories , take Jim Clark for example: F1 driver, Indy 500,British Touring Car Championship , Non championship GP races etc etc.   I guess they were used to the hard and dangerous work. The modern F1 drivers have to be engineers of sort  which maybe was not the case with their predecessors due to the relative lack of technology in their cars. As for the physical effort I believe it was far more demanding for Stirling Moss to drive the Mille Miglia in 1955 at the average speed of 155 Km/h for 1600 kilometers than it is today for any F1 driver to finish a 90 min race. Different times indeed but my hat goes off to them.
