Thank you for the opportunity to help you with your question!
The most interesting career area is Health Psychology because I can easily use the science of psychology to promote health, prevent illness and
improve health care.
I usually use my psychological knowledge to get to the root of people’s emotions to help
them make healthy choices.For example exercises and positive lifestyles to prevent obesity and high blood pressure which are brought by lack of exercises.As a health psychologist,I use psychology to explore the connection between
physical health and behavior change. The application of my research in this field
promotes wellness and healthy living.
