My grandma takes so much medication for shit, she has migraines all the time (chronic, i guess). She's very healthy though and dances like 3 nights a week. She's 82 i believe. I'd love to try and get her to toke a bit, maybe cut down on the 23904823093 pills she has to take, but I seriously doubt she'd go for it. She isn't really in a bad situation like your grandma though, so I guess it's not that big of a deal.

I hope you can help your grandma out though, I like old people. (even the crotchety ones, they're just so funny )
