In fact, not only the offspring of centenarians appear to have this protection [ 15, 16], but also do the offspring of parents who have achieved less extreme lifespans.
Once planted and installed, a roof garden runs on free solar power and protects the roof from UV rays and extreme weather, increasing the lifespan of the roof's membrane by 15 to 30 years.
However, despite their inflammatory status, centenarians reached the extreme limit of human lifespan, and escaped or delayed the major age-related diseases which share an inflammatory pathogenesis.
Such age groups at either extreme of the adult lifespan could not be selected from a single twin register.
This raises the question of whether these specific changes in the structure of the mutualistic counterpart of the gut microbiome reflect a new mutualistic configuration, responding to a microbiota-host adaptation process co-evolved to support the extreme limits of human lifespan.
Data on centenarians in particular are of interest, as they are considered the best example of successful aging having reached the very extremes of the human lifespan.
This study demonstrated for the first time that the DNA methylomes at the two extremes of the human lifespan are distinct.
In this paper we addressed the age-related differences in both the gut microbiota and the inflammatory status among different stages of the whole adult life, starting from young adults (30 years old in average), through elderly (70 years old), to the extreme limit of the human lifespan, represented by a group of centenarians (100 years old).
In particular, we decided to expand the usual target populations of comparative studies, addressing not only young adults (20 40 years old) and elderly (60 80 years old), but also centenarians, representative of a group of people who reached the extreme limits of the human lifespan [22].
