quit he was ‘so tired that I could do nothing and think of nothing for
months and it was over a year before I felt normal’. Major said it had taken
him a year to recover from the physical strain of being prime minister, and
he was only in his mid-fifties. ‘The thing about the job’, Tony Blair once
said, ‘is its utter relentlessness. It never leaves you. Never. It is emotionally,
physically and mentally draining.’

Gladstone once said that 60 should be the maximum age for prime min-
isters (although he was 82 when he started his fourth premiership). On the
other hand Callaghan, when asked the question was there ‘an age when a
prime minister should consider that he is past it?’, replied, ‘There’s no age.
It’s a case of mental condition.’

But age has a bearing on the length and
on the scope and nature of a prime minister’s post-Number 10 activities.
Seven prime ministers died in office, two as old men but five in their
forties or fifties. A further nine died within two-and-a-half years of leaving
Number 10 (most of these in their seventies). The longest-lived prime min-
ister was Callaghan, who died a day before his 93rd birthday in 2005; the
shortest-lived was the Duke of Devonshire who died in 1764 aged only 44.
The average age on leaving Number 10 of all ex-prime ministers was 61, the
average age at death was 73, and so the average post-premiership or retire-
ment was 12 years long. Advances in health and medicine help explain
why the average age at death of 18th century prime ministers was 64,
of 19th century prime ministers 74, and of 20th century premiers 81.
Four 20th century prime ministers made it into their nineties (Churchill,
Macmillan, Home and Callaghan), and only one died in his sixties (Bonar
Law). The longest post-premiership was 41 years (Grafton – who was only
34 when he left Number 10 in 1770), the shortest only 17 days (Campbell-
Bannerman, who was the only premier to die in Number 10, in 1908). Of
the 17 who enjoyed more than 15 years of retirement, only five were over
60 when they left office. No one who left Number 10 aged over 70 had a
post-premiership of more than 12 years; most of that group enjoyed pretty
short retirements.
Exhausted by work and illness, some prime ministers become old men
before their time – such as William Pitt the Younger and Lord Liverpool.
Some hit the bottle when they leave office – such as Melbourne (who would
drink three bottles of wine a day) and Asquith. But others stay remarkably
vigorous into old age. Palmerston, who died in office in 1865 aged 81, kept
his physical vitality until a late stage: jumping over railings as an old man
and getting into scrapes with young ladies. Lloyd George fathered a child
with his long-term mistress (and later second wife) when aged 66. Glad-
stone was 84 when he finally left office in 1894 – older as prime minister
than any other man before or since. In contrast to, say, the gout-ridden
and semi-invalid Lord Derby, and to the far-from-robust Disraeli, Gladstone
had exceptional physical resilience and stamina (he was still chopping
down trees into his eighties: ‘the forest laments in order that Mr. Gladstone
