Emma, The single greatest threat to our lives is not the terrorists putting poison in the water, or the pollution in the air: The greatest threat to our lives and our well-being is our lifestyle. Ask people how they are doing these days, and the first word you will hear is “busy.” Probe deeper, and soon you may see frustration as they say, “exhausted.” We do more, go more and buy more. Our gas tanks are full, our bank accounts are full and our closets are full, but we are running on empty. Surveys say we don’t get enough sleep, we eat more meals on the run than at home, we take too many pills and, worst of all, we don’t spend enough time with our children and the people we love.
