Cure's

Cure's will there ever be a cure for every terminal illness and such other diseases I saw someone wearing a diabetic t-shirt saying its ok we only have to wait 10yrs for a cure bearing in mind the t-shirt was made in 1979. Who gets to choose who has the cure should it be first given to children, un damaged people who have other health issues thanks to the disease/illness there already battling if there's so many people with the same disease or illness how is it issued. Perhaps post code lottery or first come first served, rich people against poor I really hope there is a cure for all these evil and progressing terminal illness and diseases but will you ever be cured or is it away of keeping the population down and the NHS getting into less debt??
