VANCOUVER, British Columbia — With a full-time job at the Vancouver Police Department, Meghan Agosta could easily have decided to retire from hockey this year, at age 31. Instead Agosta, a star forward on the Canadian national team, remains determined to return for her fifth Winter Olympics, in Beijing in 2022.

“We were roommates at the Olympics, and I said to her: ‘How does it feel? Is this going to be your last?’ ” said Laura Fortino, a defender who made the most recent Olympic all-star team at the Pyeongchang Games in February. “She looked at me dead straight in the face and said: ‘You know what? I’m not ready. This is not my last.’
