My mother is 73 and has 70% hearing loss, but is physically able to walk. She lives with me and my husband. The only things she wants to do is watch television, work a puzzle, and create oil paintings. She basically sits all day. When I ask her to go for a walk with me, most of the time she says no. My sister tells me to let her do whatever she wants to do. I am concerned about my mother's health. Any suggestions or should I do what my sister says and allow my mother to not get any exercises?
