It’s Friday, so here’s a sci-fi-worthy study for you… Scientists are looking into whether the blood of an athlete could help keep Alzheimer’s and other memory disorders at bay after early studies of mice have reaped some hopeful results. Lazy mice were injected with the blood of mice that love to run on exercise wheels. They found the sedentary mice performed better on memory and learning tests after being injected and that brain inflammation caused by Alzheimer’s and other disorders was reduced. It won’t necessarily work in humans, but scientists say the study supports a growing body of research supporting the link between exercise and brain health. Forget the hamster wheel, give us some of that athlete blood…
