Researchers have made an important discovery: if an elderly person is to pour the blood of a young donor, then it is possible to reduce the risk of cancer and Alzheimer's disease, and also to rejuvenate the whole organism, RIA Novosti writes.. The body reduces the concentration of molecules - markers of various ailments. In particular, cholesterol concentration decreased by 10%, cancer markers - by 20%, and the number of beta-amyloid plaques (a sign of Alzheimer's disease) - by 20%.

It is worth noting that about 10 years ago, the University of California researchers found that the connection of the circulatory systems of young and elderly rats led to the rejuvenation of the latter. By the way, three years ago, other researchers conducted a similar experiment, overflowing the "young" blood to mice. As a result, the brain of the recipients was rejuvenated, which reduced the likelihood of developing Alzheimer's disease.

However, everything is not so clear. For example, two experts - Irina Conba from the University of California and Tony Wiss-Koray from Stanford University - repeated the experiment, but came to different results.
