Every day when you awaken you reach into the bowel and take out a jelly bean and eat it. The white jelly bean represents a good day. The grey jelly bean represents a close call where you almost buy the farm but you live to eat another jelly bean. The black jelly bean is the day you die. You never know what color it is until you eat it.
Some folks grab the black jelly bean early in life.
Others empty the bowel and get down to the last one. In any case we all have to eat the black jelly bean. In aviation we always said the amount of air above you doesn't matter. It is only the height of air between you and the gound that counts. In other words, don't worry about the tomorrows because they may never get here.
