I remember a fellow crew member, many years ago - used to turn up after days off with little bits of what looked like sticking plasters stuck to his ear, we assumed he'd had an accident and (unlike us) left it at that, then we realised the sticking plasters had become a permanent fixture so we tackled him. He had always had a problem with seasickness so had been advised to go and see an acupuncturist - the 'sticking plasters' held grains of rice in place, whenever he felt a bit queasy, he would rub these patches and the nausea would abate, he swore they worked, saved a promising career.
