Why does Ed Sheeran think Taylor Swift is like a middle aged woman?

Ed Sheeran thinks Taylor Swift is really an old soul. Here's what he said about his friend: 

"I know she's 24 but she's a sort of middle-aged woman trapped in a 24-year-old’s body. She hangs out with her cat and sews things."

So how old does Ed think he is when it comes to his soul? 

"My soul age differs from day to day. It can be 8 or 80. It just depends on what I'm doing. If I'm working it's usually pretty spot-on for work, but if I'm with my friends and the clock's off I'll go back to being young."
