Because it might be overlooked in the middle of all the other good ideas, I want to stress the importance of thanking our professional caregivers, every day, after every treatment, no matter how we feel. They have chosen to work with sick people, and every person I see is friendly and helpful -- and overworked. As a former health care worker with critically ill people, I know how much a smile and a sincere thank you mean. So patients and family, do not forget to thank these hard working people whose goal is to save your life.
