I think many with cold feet and hands or restless legs might find some help by using magnetic therapy. My husband (62/12) has found that they increase the strength in his arm on the parkinson side. He used two mini's on his arm, insoles in his shoes and sleeps on a magnetic pad. Anyone that would like more info can Email me. We live in Montana on a ranch so he is out in the cold daily and I've never heard him complain about cold feet or hands. Nancy
