Can spending less time sitting down add years to life?

They don't know. Why ask?

Limiting the time we spend sitting to just three hours a day could add an extra two years to our life expectancy, scientists calculate.

Similarly, if we cut daily TV viewing down to two hours we could add on 1.4 years, they say in a report for the online journal BMJ Open.

But experts say the US estimates, which are based on five separate population studies, are too unreliable to predict personal risk.

Plus the targets are unfeasible.

Well, that was helpful.

More crap research.
