In reply to Archmagos_Dominus:
I read/watch/heard something about grip strength being a good indicator of general health about four years ago.
I was so intrigued that I bought a "grip-o-meter" (dynamometer), we had great fun testing everyone in our clubs grip strength, it turned a bit competitive!!
£15.85 from Ebay, (it's the same as the ladies in the articles), I made a cover to be able to measure fingers only grip.
I even have a spreadsheet of the contest results, it might be interesting to revisit and see what's happened in the last four years.
