What if you could extend your healthy life by 10 or 20 years – with a blood transfusion from someone younger and healthier than you? Research by Stanford professor Tony Wyss-Coray shows potential to treat Alzheimer’s and prevent age-related cognitive decline: He’s discovered that proteins found in the blood of young mice can dramatically reverse the effects of aging when transfused into older mice. Doing the same thing in humans could increase our quality of life as we age, and our life expectancy too. We’re years away from seeing any clinical applications of this research, which gives us time to ask about its implications. Who will have access to this treatment? Who are the donors providing young blood? We could add years to our lives – but is that what we really want?
