When Dr. Nir Barzilai met the 100-year-old Helen Reichert, she was smoking a cigarette. Dr. Barzilai, the director of the Institute for Aging Research at the Albert Einstein College of Medicine, recalled Mrs. Reichert saying that doctors had repeatedly told her to quit. But those doctors had all died, Mrs. Reichert noted, and she hadn’t. Mrs. Reichert lived almost another decade before passing away in 2011.
There are countless stories about people who reach 100, and their daily habits sometimes flout conventional advice on diet, exercise, and alcohol and tobacco use.

Research suggests that making it to 80 or even 90 is largely in our control. “There’s very clear evidence that for the general population, living a healthy lifestyle” does extend the life span, said Dr. Sofiya Milman, a professor of medicine and genetics at the Albert Einstein College of Medicine.
