Blood drawn from a young person can help revitalize health that fails in the elderly, after studies in young mice.
Professor Linda Partridge of UCL's Healthy Aging Institute has drawn from human and animal research and argued that humanity is gaining tools to prolong health.
His argument in the journal Nature comes in the middle of a Harvard University company that announces that it would invest millions to explore the treatment based on the idea that the blood of young animals can help the elderly.

Professor Partridge told The Telegraph: "I would say that aging is the emperor of all diseases.
"There has been all this fantastic research on animals.
"We're really starting to understand what malleable aging is like, now we have to push to translate this into humans."
The research carried out in the area has already found that when the blood of a young mouse is transfused in one when it is sick, it can help maintain vitality.
The professor's arguments follow an investigation conducted in the area that has found that the blood of a young mouse can help maintain the vitality of an older mouse
In 2014, researchers at Stanford University led by neuroscientist Tony Wyss-Coray discovered that the infusions of blood from young mice reversed the cognitive and neurological impairments observed in older mice.
This research now investigates how humans can benefit from animal studies.
A US clinical trial called Ambrosia is already offering teen blood to senior clients at a cost of $ 8,000 for 2.5 liters and this week saw another program called Elvian announce that it had a $ 5.5 million investment backing to conduct research in the field.

Their scientists, biologists at Harvard, are exploring whether a blood protein called GDFII is the key ingredient.
While it is too early to say whether any of the companies could benefit their clients, Professor Partridge said that other forms of intervention were needed with diseases of aging that would threaten the bankruptcy of health services.
However, blood is not the only thing the elderly can take to maintain their health, with Professor Partridge also suggesting that bacteria taken from a young person's intestine can help the "microbiomes" that work poorly in the elderly.
