According to Icelandic singer Bjork:
Maybe there are a lot of kids now who don’t know how to walk in a forest and do basic outdoorsy things. You can be on Facebook for a long time, and then you get a feeling in your body like you’ve had three hamburgers. You know it’s trash. I always advise my friends: just go for a walk for an hour and come back and see how you feel then. I think we’re meant to be outdoors.
