Virginia Webster, age 71, lives alone. One side of her body is paralyzed, but she still manages to fend for herself at home. One night in 1981, she fell down and couldn't get up. She struggled to crawl, inch by inch, to the telephone in the next room. The sun had already come up the next day when, in agony, she finally reached the telephone and called for help.
