I'm Khaled, a final-year medical student, and I make videos on quite a few different topics within the scope of medicine such as reacting and breaking down medical shows, studying for exams, discussing important health issues, etc... I hope that my videos help you in any way, shape, or form and that you enjoy them regardless of your background. Medicine is quite the challenging topic, but I don't see why we can't enjoy it together!
