I thought I would get a little more informed about the state of life extension technology and dug up this Guardian article on various drugs and techniques being investigated. This section stands out.
One of the more unusual approaches being tested is using blood from the young to reinvigorate the old. The idea was borne out in experiments which showed blood plasma from young mice restored mental capabilities of old mice. A human trial under way is testing whether Alzhemier’s patients who receive blood transfusions from young people experience a similar effect. Tony Wyss-Coray, a researcher at Stanford leading the work, says that if it works he hopes to isolate factors in the blood that drive the effect and then try to make a drug that does a similar thing. (Since publishing his work in mice, many “healthy, very rich people” have contacted Wyss-Coray wondering if it might help them live longer.)
As I age, I often find myself looking at the supple bodies of young people and musing on how I would like to drink their blood. It’s good to see I’m not alone.
The last sentence in that quoted paragraph touches on what got me thinking about this. In some sense, death is the great equalizer. Are we about to enter an era where income inequality will correspond with lifespan inequality? Technically, I think we are already there though the disparity is minimal.
It seems a near certainty that in the future the aged wealthy will be kidnapping young people off the streets and harvesting their blood.
