I disgree with the sub-point about plan-making. I'm 50, but thanks to health issues^[thanks to undiagnosed ADHD and our lack-of-healthcare system in the US] I'm not likely to last another decade^[Six heart attacks, a pulmonary embolism, kidney failure so I'm on dialysis]. But while I do think about my probable looming death somewhat, I don't fail to make any plans because of it. As far as I'm concerned, I'm going to live forever - until I don't. I mean, that's what my brain thinks.
But I don't think most of them probably think about death until they get ill.
I'm not so worried about old people in politics - I think there should be a mix of young and old. You need strong young voices pushing for progress, and you need old experienced voices who have seen all this shit before and know how to deal with it.
What we don't need in politics is control by our oligarchs, which is what we have now that's broken our democracy.
