I came across this study based on Spanish data and thought it might be relevant here.
“We show evidence that delaying exiting employment increases the hazard of dying
between the ages of 60 and 69, for almost all individuals. Heterogeneous analysis indicates that
the increase in mortality is stronger for those employed in low-skilled, physically and psycho-
socially demanding jobs. Moreover, we show that allowing for flexible retirement schemes,
such as partial retirement, mitigates the detrimental effect of delaying retirement on mortality.”
