kim davidson: i was freezing cold, and i didn't bring a jacket that day. and i felt these little hands up on my shoulder and a sweater come up around me. and i turned around, and it was lynsie. and she said, i just can't stand sitting here watching you shiver. josh mankiewicz (voiceover): and lynsie gave back in other ways. her mother says lynsie would lie about her age so she could give blood. remarkable in itself because lynsie struggled with her own disabilities. her left arm was paralyzed. her left leg, impaired. josh mankiewicz: did she ever talk about how she became disabled? she had brought it up to me and said that she was in a car accident and that she was thrown when was a little girl, but very, very, just matter of fact. josh mankiewicz (voiceover): but growing up, lynsie needed so much care. her mother, nancy, was with lynsie-- like her shadow. nancy ekelund: she was my only purpose in my life was to make her as normal as she could be. josh mankiewicz (voiceover): by the time kim met lynsie, lynsie's dad and brothers had moved away. kim remembe
