Felice Shapiro needed an escape from the shadow of a daunting transition. At 47, Shapiro had just lost her husband and was about to send her youngest of two sons off to college. Shapiro found herself seeking solace in her friends. “Women tend to find comfort by sharing stories, connecting, supporting each other,” said Shapiro, who teaches entrepreneurship at Tufts University. Inspired by that notion, she set out to establish an online forum for 50-somethings to convene in times of adversity and success. Last November, Shapiro launched Betterafter50.com, a weekly interactive magazine encouraging women to find a second wind mid-life — and share their experiences along the way. As Better After 50 approaches its first anniversary, Shapiro talks inspiration, the mind-set of a “BA50,” and what’s next.
