Do genes determine lifespan?

Genes are telling us even more about our health. Research out today suggests that there are about 150 genetic variations associated with living to 100, and that scientists could tell with 77 percent accuracy whether you will become a centenarian one day.

The study is in the journal Science, comes from Boston University Medical Center and Boston University School of Public Health. Study author Thomas Perl says more research is needed to figure out how exactly the genes associated with longevity work. If scientists can understand more about what those genes do, they might be able to one day create a medical therapy to imitate that function, so that more people could live longer.

But genes aren't everything - lifestyle choices such as diet, fitness, and avoidance of smoking are still important in determining how long you will live.

    How very ironic, a modern day Republican evolutionary life adaption.

    With a recent 5 year study performed by a sizable group of researchers that collected whale tissue for sampling without harming the whales found extremely high levels of toxic heavy metals Mercury, Lead, Cadmium, Titanium and a wide range of pesticides calling into severe doubt that Whale meat was even safe for humans to consume.

    Whales which mostly feed on the lowest section of the food chain in the world's Ocean (krill), are a fair and accurate biometric on how toxic and contaminated seafood and fish have become in the past decade of Republican corporate dumping of hazardous waste into the world's Oceans.

    As I have stated here and in other places on the web in the past, I find it entirely ironic that the very toxins that evil people, countrys and corporations have dumped into the Oceans could very well end up with mass numbers of commercially sought fish species being so contaminated with pesticides and toxic metals they are entirely deemed unfit for human consumption and slip further to deemed unfit for pet consumption.

    So many country's around the world entirely depend on seafood for nearly all of their protein consumption and this would lead to mass starvation around the world if seafood were largely unsafe and harmful for humans to consume.

    Ironically many species that are greatly over-fished by greedy Republican led corporations would likely recover leading to their toxic protection against human consumption, a modern day Republican evolutionary life adaption by fish protecting them from humans, go figure!
