As some know here, I am a retired cop (30 years).
I am a member of NARPO (National Association of Retired Police Officers) - UK.
It seems that hardly a day goes by without an e-mail from my regional branch with details of yet another brother or sister officer who has died. Not so many in the line of duty (this is the UK) but within a very few years of retirement.
Do we all just get so worn out by the shit we dealt with that we can't take it any more?
Me, I do my best to move on but I know of colleagues that can't.
