Anecdotally I've observed older people around me who retire early for various reason have much earlier decline in both mental and physical health. Where as the ones that work until much older age tends to be healthier. And it does seem causal too, since the decline doesn't happen until years after retirement. For example, many of my aunts and uncles that retired around 55 - 60 are / were having many health issues some have experienced decline in mental sharpness. Where as my grand parents who worked on the farm until into the 70s were fairly healthy until towards the end of their lives.
