People die every day; it's a natural part of living. Sometimes death comes as a surprise brought on by an accident or sudden illness. Sometimes death lingers for years like a foul odor that can't be scrubbed away, or it hangs like a gray cloud over family holidays and gets in the way of summer plans, because no one knows when it's going to strike. Beverly Seaton Ingersoll, 58, knew her husband Larry Seaton was dying. He was a decorated Vietnam veteran and a stoic, disciplined, hard-working man, she says. When he was diagnosed with rapidly progressing lung cancer that already had metastasized to his brain, doctors weren't sure he'd live through his first night in the hospital. But he hung on through four months of surgery, ups and downs, close calls and sudden changes.
