90% of medicines don’t work for 30% of people, so in the future we’ll see treatment programs and drugs tailor made for specific groups and even individuals. We’ll also see diets customised to specific groups of people and genetically based treatments. Fast forward to the year 2033. After supplying a sample of blood you receive an email from the supermarket telling you what you should and shouldn’t eat to extend your life by twenty years. This diet will not be totally unique because you’ll share certain characteristics with other people (for example, different ethnic groups have different food intolerances). In the ‘average’ groups such diets will be unnecessary, but for people with problematic DNA profiles treatments will be highly beneficial.
