Slightly on topic, but yesterday I discovered that I'm the same age as Rishi Sunak, and it's fucking with my brain that I'm the same age as the Prime Minister. Something about that just ain't right.
Older age isn't necessarily a negative factor in leadership, but I know what you're saying. However, I can't deal with the fact that I'm 43 and don't feel like a grown up, so does that mean our Prime Minister feels the same way about himself? I can't square that circle, y'know?
I don't know about Sunak specifically, but generally the types of people who succeed at politics have way too much unjustified self-confidence to introspect that much.
I think it also ties in with the "olders and betters" mentality that we're brought up with. There's a sense of gravitas to the office of Prime Minister, and even if they're doing stupid shit there's a monkey bit of my brain that's like "ah, but they're old enough to know better than me". But now the PM is only four months older than I am, and my mum worked for his dad for a few years, so we could have (theoretically) turned in the same circles*, and he's up there in the highest office in the land, doing stupid shit and I'm looking at him and wondering who let this idiot kid be in charge.
*We really couldn't have though, he went to a very fancy school and was already married to a billionaire by the time my mum started working for his dad. His dad's actually sound.
