People always say they love the smell of the great outdoors and the forest.
Part of what you smell is what you aren't smelling anymore when you leave the city.
Plants and trees absorb Carbon Dioxide and expel pure oxygen. The closer you are to lots and lots of trees the more...
I love to breathe the air in the woods... it's thick, sweet, and warm. Smells of honeysuckle and is very moist, so it's like breathing in air from a humidifier. lolI gues that doesn't sound pleasant, but I grew up here, so I love it. :)
