On the introverted end. I'd just walk around downtown listening to music, not a care in the world, just looking at my surroundings and taking it all in. Sometimes I'd even make conversation with strangers here and there, though it was mostly brief.
I'd drink coffee or tea as I walked, and one of the main benefits of that was that it kept me fairly in shape.
Now I struggle to make the time. With work as a factor in the equation it's not been as easy. But fuck do I miss my aimless walking time. And I miss the good shape it got me in. Walking daily really does make a difference in terms of keeping off the pounds!
