Original question: "How many years do you expect to be a caregiver over your lifetime (enter total number even if it spans more than one person you are/you might be caring for at different periods in your life and including anyone you have provided care for in the past?"

Definition of caregiving in the C.A.R.E. Study: Situations where an individual is responsible for providing care (emotional, financial, physical) or the resources for that care to someone or several people over a substantial period of time. The caregiving could be for anyone in their life who is or could be aging, ill or have special needs, but does not include any caregiving that is done in a professional capacity/as part of employment.
