No animal eat on the run. Not lions, tigers, or bears. Cows, sheep, and goats meandered as they grazed, but only humans walk and eat at the same time and most of those achieving this dubious goal are Americans. Every morning I share the train with commuters holding hands with a cup of coffee or else stuffing their faces with a bagel. I was probably guilty of the same sin in inetiquette prior, but have cut down the occasions to the rare scarfing down a slice of pizza, when i have to be someplace.
Even I'm not perfect.
We are what we eat and even more so how we eat.
Fast food makes for fast eating makes for fat people.
