When I used to take walks at my favorite nature sanctuary, Mt. Auburn Cemetery in Cambridge, Massachusetts, I often thought to myself, “This is paradise,” as I gazed up at the towering oak and maple trees and listened to the varied birdsongs. Now that I live in Florida, I find myself feeling much the same way. Each morning after sunrise, I walk the nature trail that encircles the perimeter of the community where we live, enjoying the palm trees and flowering bushes and the calls of birds that make Florida home. This morning at the end of my walk, another walker passed me, said “Good morning,” and commented, “Another day in paradise.” I laughed and agreed with him. Most people I pass on my walks make some similar comment about the beauty of the day.
