The second scenario is what we call 'The Wolverine' or the Fountain of Youth: taking old people and make them young. This is very, very hard, this will be the most complex things we can do. And the third scenario, and this is a very exciting scenarion, and we have some evidence that it works, is the Peter Pan scenario. Peter Pan didn't grow old- the idea that you take people when they're 20 or 30 and give them a treatment every few months or every year. And you'll basically erase their aging and let them age very, very slowly, which aslo will mean probably that they'll pass their 115 year maximum potential lifespan. 

Dr Barzilai's third treatment involves slowing down the ageing process so much that people hardly age at all. This treatment is called Peter Pan, after the fictional boy who never grew up, and is connected to another idiom, Peter Pan syndrome, which describes an immature person who has reached adulthood but refuses to take on adult responsibilities.
