Good news I expect? It was for me at least.
The study says we control this ability to live longer because it is all in our heads; and this is backed up by numerous other studies.
These UK researchers used data from a long term study on ageing which included 6,489 individuals. They asked them if they felt their actual age, or older, or three to four years younger. [Interestingly, the average chronological age of the group was 65.8 years while the average self-perceived age was 56.8 years.]
After 99 months (just over 8 years), the researchers went back and checked how these people were going. They found that those who said they felt older than their actual age were 41 per cent more likely to have died than those who said they felt younger.
