What is the disease from which 30 million people suffer worldwide, and will increase to 130 million by 2050? In Britain, the number of sufferers will be around two million. No one fully understands the details of this disease, and there is no cure. It is an immensely costly disease for the state, and for the families of sufferers. In one case known to me, the out-of-pocket costs to the family were £300,000. Despite the lack of knowledge and the immense cost, research into alleviation is substantially underfunded compared with cancer and heart conditions. And, by the way, one in six of those over 80 will get it. That means you, unless you cheat by dying earlier.
