Green makes you smarter, healthier

A colleague of mine boasted long ago that he got an hour’s exercise every day by walking through SM Megamall, and he did it as soon as it opened, when it wasn’t too crowded yet. “And I don’t get bored,” he said.

I tried it once, but I felt extremely exhausted. I could sense something was really off. Now I know what exactly is the matter, and it’s not just because I breathe stale air recycled a hundred, even a thousand times a day.
