"I think everyone who's worried about their health should dedicate at least half an hour a day to exploring a park outside their house."

Oh? Spoken like a city slicker! I tell you what!

Not everyone lives in a city near a park. Some people would have to walk for days through fields and forest and brush just to get to the nearest park. How do you expect for them to get their dose of nature, hmm?

Check your urban privilege!
