Thank you. I think they put "being" in the wrong place and actually meant: "Conversely, subjects reporting slow walking pace had shorter life expectancies, the lowest being observed in slow walkers with a BMI less than 20 kg/m2 (women: 72.4 years; men: 64.8 years)." So if you're really frail and can barely walk, it doesn't bode well for you. What if you're healthy, low-weight, and walk slowly?? Presumably the full paper contains that info, but I'm surprised it's omitted from the abstract.
