As discussed earlier, in most populations, our longevity is now well in excess of that experienced by members of our species even in recent times: for example, life expectancy at birth for women in prerevolutionary France was about 35 but has more than doubled today (Fogel 2004).
Even though genetics play a major role in our health longevity, genetic screening and advancements in diagnostics over the last few decades have changed the landscape dramatically.
While we won't all live to age 100, we can make changes in our lives to improve our longevity with the added benefit of improving our current quality of life.
So, in our world of longevity, where over-65s are living longer than ever before, my grandson's angst intrigued me.
In his book Play on: The New Science of Elite Performance at Any Age, the US sports writer Jeff Bercovici investigated the training regimens of Williams and Federer, among others, and he found that the methods by which they play and stay fit in their older years have relevance for us all in our quest for longevity and fitness as we age.
When Paul Ryan declared that along with his leadership, "I cannot and I will not give up my family time," he was also paving the way for the flexible work we are all demanding in our era of longevity.
Actually, in our GWAS for longevity we discarded the Affy500 data set because of the small number of reliable SNPs.
Thus, it is likely that LCA and all other novel anti-aging compounds identified in our screen target longevity-related cellular processes that are not modulated by the presently known anti-aging small molecules.
In conclusion, we have shown that the deleterious effect of the ApoE ε4 allele, tagged by rs2075650, is the single major hit in our GWAS study for longevity, indicating that no other major longevity locus was present among these nonagenarians.
Importantly, regenerative procedures could eventually promote tooth longevity in our aging population.
