The project is based on Design for Behaviour Modification. The selected field is routine health checkups. Routine health checkups are meant to comprehensively perform various tests on a person periodically so as to prevent illness or take action whenever necessary before the illness gets aggravated and caught at a later stage. Health checkups are especially important for middle-aged people who tend to fall sick often. However, most people do not do this regularly for varying reasons. The aim of the project is to understand the mindset and behaviour of such people and intervene by providing nudges to benefit them so that they go for routine health checkups regularly. To do this, various cognitive biases in the human brain were studied. Several examples of nudges in healthcare and other fields were studied for a better understanding of various biases. In the end, some ideas have been described to try and make health checkups more routine in the lives of middle-aged people.
