Why are these men smiling?
From this article The helmet that could turn back the symptoms of Alzheimer's:
“An experimental helmet which scientists say could reverse the symptoms of Alzheimer's disease within weeks of being used is to be tried out on patients.
The strange-looking headgear - which has to be worn for ten minutes every day - bathes the brain with infra-red light and stimulates the growth of brain cells.’
The treatment is described as potentially life changing – just ten minutes a day. Buy a helmet and get a copper bracelet as an added bonus. I hope the helmet works; we'll see.
