Theresa Nist is revealing her ways for combating stress days after ex-husband Gerry Turner released his tell-all book. "I wanted to talk about stress. I wanted to talk about how much stress - a little bit of stress can be great, but a lot of stress and a lot of chronic stress can really take a toll on your body," Theresa, 72, shared in a Sunday, November 9, Instagram video. Theresa explained that she tends to "take a deep breath" and think about "all the wonderful things" in her life that she is "grateful" for - including her family - when she is particularly overwhelmed.
