Stacey Dooley. She does incredible documentaries – in one, she took spoiled British kids to the Philippines to work in a factory. It’s exactly what my kids need to watch.

I love and admire Julia Roberts, one of our Running Wild guests, for the way she has a few close friends, is loyal to her family, doesn’t believe in all the fame stuff and can laugh at herself.

Michelle Obama. Her girls were massive fans of So You Think You Can Dance and we were invited to the White House for the Easter egg hunt. She was even more brilliant than you imagine, and we bonded over a love of Beyoncé.

Greta Thunberg.

When I was 16, at the beginning of the summer vacation, I worked in a factory that made industrial valves and I was a much worse industrial valve producer than historian.

That I still don’t understand life. When I was young, I thought at some point I would find somebody who does. I am 45, and there is a good chance that I’ll never meet somebody like that.

I was almost run over by a bus when I was 13. And in 1991, in the Gulf war, an Iraqi missile hit close to my house.

Now. I’ve learned to adjust my expectations to reality better than when I was 20 or 10.

When my dog died a couple of years ago. We were in Greece on vacation and a friend was watching her at home, and she was bitten by a snake. We rushed home, but we were too late by a few hours.

I would like to come out at 16 or 17, and not 21.
