Couch potato lifestyle may speed up ageing

Being a couch potato in your free time could make you a decade older biologically than someone who is physically active, according to a major study of people’s “chromosomal clocks”.

Tim Spector at St Thomas’ hospital in London, UK, and colleagues measured the lengths of telomeres – the DNA that bookends our chromosomes – in the white blood cells of 2401 twins.

Telomeres shorten each time a cell divides, and when they become too short a cell can no longer divide, so telomeres act as a kind of timer counting down our biological age.

The researchers found that people who did not exercise in their spare time had shorter telomeres than very active people.

      The oligarchs openly talking about a coup d'état in America?
     

    Multi-millionaire lobbyist Grover Norquist is calling for the impeachment of President Obama. In an interview with the right-wing National Journal - Norquist warned that if President Obama wins re-election and decides to let the Bush tax cuts for the top 2% expire at the end of the year - then Republicans will "have enough votes in the Senate in 2014 to impeach [him]."
     
    What does that mean? It means that the super rich in America - and their political operatives like Norquist in Washington, DC - have now compared a tiny tax increase on the wealthy to high crimes and treason - the only Constitutional basis Congress can use to impeach a President. It sounds like the oligarchs are now openly talking about a coup d'état in America.
