WGBH and AARP are co-producing a web-only reality series, 5 Weeks to a New Life, focusing on “revitalizing a marriage and other relationships, staying sexually active throughout life, looking good without resorting to Botox, financing dreams and living a life with purpose,” they said in a statement. The program follows two married couples and four singles facing the challenges of middle age, with guidance from personal-growth experts. The content “was designed not only to spark our thinking about what we want, but to inspire us to move forward,” said Laurie Donnelly, executive producer of WGBH’s lifestyle programming.
