I curious how much people dying of a broken heart plays into that?

My sister whose an MD said it was a known thing that when people get up there in age, it’s not uncommon for someone to pass relatively soon (taking like within 5 years) after their partner passes.

For some people it can be days/weeks if they’re not in good health, for others it can be years.

I think it’s a similar reason to why folks will often struggle with memory after their partner passes; in lifelong partnerships people build shared memories where one half will remember some details which the other half won’t and visa versa. That and the decline in socialisation, human interaction combined with the depression and isolation that follows the passing of a partner.

I’m curious as to whether people who lose their partners whilst still relatively young (40s) experience the same decline in life expectancy, and whether them having children correlates with higher life expectancy or not in those scenarios.

I don’t quite remember what they’re called but in the UK there’s both old mining trains and old cliff trains/trolleys that use toothed wheels and toothed tracks on the hill portions to go up/down hill with little issue, obviously it’s only safe for some gradient, but still with the right gearing it would be of possible
