Why is Charlie Angus not running for NDP leadership?

He's vocal about the NDP heading in the wrong direction, he seems to have a recent swell of popularity after the Trump threats, he's about 62, which is only two years older than Mark Carney (I mean, look at Biden and Trump's ages). But instead, he didn't run this election. He probably had valid personal reasons or something, so if that's it, I guess that explains it, not trying to be nosy. But he just said spending time with family, which, well, that's what Sean Fraser said too (I guess Sean Fraser doesn't have a band, maybe that changes things).
