>If one’s thirties were a decrepit old age, ancient writers and politicians don’t seem to have got the message. In the early 7th Century BC, the Greek poet Hesiod wrote that a man should marry “when you are not much less than 30, and not much more”. Meanwhile, ancient Rome’s ‘cursus honorum’ – the sequence of political offices that an ambitious young man would undertake – didn’t even allow a young man to stand for his first office, that of quaestor, until the age of 30 (under Emperor Augustus, this was later lowered to 25; Augustus himself died at 75). To be consul, you had to be 43 – eight years older than the US’s minimum age limit of 35 to hold a presidency.
