Physical Wellness: Why Do We Still Hurt Ourselves?

I was recently reading THIS article from Gallup that breaks down how much the largest American employers spend on smokers and obese employees and how much money they lose every year from these employers and it got me thinking, why do we keep hurting ourselves. E and I always seem to have the same reaction when we see someone smoking or chewing, why would you do that? In this day and age and with all the research that shows just how bad tobacco is…why do people still start? Why do we still engage in behaviors that are harmful to our health and that we know are harmful? Furthermore, why do we still eat all this chemically processed food that we know is bad for us?

Why do we still engage in behaviors that are harmful and have no benefits to them?
