Again? I think I still do it all the time, although now I also know what it means to see through an adult’s eyes.
I used to think solo travels helped see the world through a child’s eyes but actually relocation may be the best way to keep you fresh and young.
Start a new life in a country of different language and culture. House hunting, finding the nearest supermarket and pub, making new friends, getting lost…
It is a bit like re-experiencing childhood, that strange and exciting world.
If you want something more instant though: weed and chocolate.
