All people in life at some point are care receivers and most end up caregivers. During the care receiving, we're usually in a position of vulnerability—we can't do it for ourselves. That's a universal state from time to time in our lives. That's what they have in common.
Most seniors and handicapped people still want some autonomy about, “Okay, so I can't walk and I can't feed myself, but I sure want to have some choice in my life, so could you let me at least choose my caregiver?” In B.C. they had a Human Rights Tribunal case, the Hutchinson case, a few years ago. The government there would fund anybody but the dad to take care of her. The Human Rights Tribunal said, “Excuse me, we have to fund the dad if that's who she wants.” What they have in common are the rights of the care receiver.
