Beginning A few years ago — well before I retired last month — my colleagues and I started a blog to which we have all been contributors over time. When we launched “Practice Makes Possible, ” I wondered who would be attracted to a blog that only had one post. But that first post was like a seed. We planted it into dark virtual earth. Little by slow, the blog grew. One post at a time. That’s how life begins — yeast, fungi, apples, octopi, you, me. In the dark from single cells.
