Supporting (1)
People who had trouble using their arms and hands were more likely to die over the next 23 years, even after accounting for other health problems — suggesting weak arms can be a warning sign that the whole body is declining.

Hand muscle strength in Parkinson's disease: A Sarcopenic epiphenomenon or a meaningful biomarker?
This study looked at hand strength in people with Parkinson’s and found that when their hands get weaker, it’s because their brain disease is getting worse — not because their whole body is declining. So it doesn’t support the idea that weak hands mean you’re more likely to die from anything.
