can u please suggest a course which is for taking care of grand parents

Grandparents are like your siblings. Their age is just a number with a heart of a kid like you. You don't need to follow a prescribed method tl take care of them. Just give them your time, automatically they will be the happiest. Make them laugh like they did you when you were a toddler. Go for a walk with them, holding hands like they did when you learned to walk. Tell stories to them, like they did when you didn't sleep. Feed them with candies and junks. It' ll not harm their health much. And most importantly love them. They are the best friend you can have. You know their value when they are gone. Like I do.
