Results from a new survey have revealed how men turn the grumpiest when they hit their 70s.
Until the age of 65 experts believe that men become better at shrugging off stress and anxiety the older that they get.
Four-fifths told researchers the difficulties that they encountered from the age of 50 receded but then upped again after 70, the Daily Star reported.
20 per cent reported a surge in happiness from retirement age until 70, then they too experienced a downturn.
Professor Carolyn Aldwin, of Oregon State University, said that once people turn 70, how they react to these hassles changes and may be dependent on their resources or their situation in life.
The study looked at 1,315 men aged 53 to 85.
The study has been published in the journal Psychology and Ageing.
