Six months after his girlfriend’s death, Clint Eastwood is “doing good,” according to his son. Eastwood’s girlfriend, Christina Sandera, 61, died of a heart attack in July, the two were dating for 10 years. At the time, Eastwood said: “Christina was a lovely, caring woman, and I will miss her very much.” His son, Scott, told PEOPLE that the legendary director and actor was a “survivor, a trooper.” Sandera passed away just two days after her 61st birthday in a Monterey County, California, hospital. She was a board member of the Monterey Bay National Marine Sanctuary Foundation, who paid tribute to her at the time of her death on Instagram. “Despite being connected to high-profile celebrity life, Christina often eschewed the spotlight. She was far more comfortable in her jeans, pigtails, and baseball hat, shoveling and tending to her beloved horses and animals.” Scott said of his father that it was in their blood to “just do.” He said his father “was born coming out of the Great Depression, and then he was young during World War II. He saw a lot of struggle...There is no room for complaining.”
