Yes. In a way, that's really a metaphor for what goes on, all the time -- not just with gravity, but with everything we need to survive. A few days ago a baby squirrel somehow found itself in my back yard. Presumably it tumbled from some overhead branch. The dogs knocked it around a bit before I could attempt a rescue (by placing it over the wall into my neighbor's yard). Despite my intercession, I suspect that squirrel won't be passing its genes on to the next generation.
