This boxer is using science to track her brain health, and helping researchers better understand head impacts
Claire Hafner's chin is tucked in protectively behind her gloves. Just above them, her eyes are laser-focused, looking for an opening. Her arms shoot out like twin pistons, forcing the solid teen powerhouse she's sparring with to retreat against the ropes.
At 46, the Edmonton-based boxer is mulling over retirement but wants a Canadian title before she throws in the towel.
"It'll be hard to hang up the gloves without checking that box," she said.
That decision hangs largely on what a team of researchers in Las Vegas find when she meets up with them for exhaustive annual testing on her brain health.
