Power balance

When last we saw my brother and his wife back in September they were extolling the virtues of the new "Power Balance" bracelets which were available from lots of pharmacies and chemist shops in Sydney and the Central Coast. They were supposed to restore the body's natural balance, unlock energy flows and generally help make the wearer feel "great". I think I saw earlier this week, in the paper, that they (the bracelets not my brother and his wife) have been exposed as a "sham". That may be so but it seems they may have a strong placebo effect as lots of their friends have reported feeling better when wearing them.
