"Could have been Jesus … I sort of figure, you know, that when your number's up, your number's up. It'll happen one day, and I don't think there's much point worrying about it," he said.
McCartney may have come to terms with his own death, but he said that having a young child at this point in his life makes him view things differently.
"Yeah, you think about it," he said. "But, I mean, that's nothing surprising. I thought about my dad dying when I was little. … I think it's just human. I want to be around."
"It's really interesting to be grateful for what you've got," McCartney said about "Gratitude," another single from "Memory Almost Full."
"I think a lot of times in life we concentrate on what we haven't got. We're a bit fed up, it's a bit cloudy today. But I like very much to think, 'Look at what you have got. And there's so much.'"
