Are we, as human beings equipped to deal with excess, whether it be excess of food or wine, excess of entertainment, excess of money, excess of pleasure in all forms? I have just subscribed to Netflix and am now ready to indulge in some serious binge watching, but I can't quite decide whether I came too late to this game to feel anything other than guilt. My grandchildren, on the other hand, seem at ease in marathon sessions  à la Las Vegas. Where is it all going to end?
