Although I'm somewhat sympathetic to the view that journalists (even BBC journalists...

) often seize the most eye-catching fact out of these reports and inflate them to headline size, in order to create a piece that's newsworthy (i.e. suitably novel to catch the eye of the casual reader), that is after-all, their job - it's a consequence of their work that we're discussing this at all!
However, with due respect, Beardy, the scientists are simply
stating the obvious - well, obvious now it's been the subject of a wide-ranging peer-reviewed study... as opposed to missing it.
And don't go rushing off to buy springs, folks - this is only an
indicator.
from the study...
Interpretation
This study suggests that measurement of grip strength is a simple, inexpensive risk-stratifying method for all-cause death, cardiovascular death, and cardiovascular disease. Further research is needed to identify determinants of muscular strength and to test whether improvement in strength reduces mortality and cardiovascular disease.
