Florence SeeSee Rigney celebrated her 90th birthday in the hospital last week. Oh, she’s in good health. In fact, she was working! Rigney is the oldest working registered nurse in the United States, putting two days a week at Tacoma General Hospital in Washington state. After 60 years of taking care of other people, you’d think she’d be ready to retire, but Rigney loves what she does. -via Viral Viral Videos
