I am a hospice social worker. This very topic has been very near my heart for so long. I am thankful for the work being done through this movement. I would suggest those who are interested in further engaging a loved one in such a conversation, look into the Go Wish Cards. They are a great tool that allows one to express their wishes in case they face a serious illness. They are simple and user-friendly. They are also available in Spanish.
