Hi Dalal,
     Your thread made me very emotional. You are very lucky that you got a warm love of your grandparents till this age. I was not that lucky to get love and care of my grandparents because my both mom's and Dad's parents died when they were kid. I just saw them in the picture (mama ghar ko hajur buba matra) and rest of them don't have picture since there is no tradition of taking picture at that era. 
    At this moment of life I used to donate money in their name. Recently i did donate money to one very poor kid from Philippines for her surgery in my grand mother name.
    If i were you, I will always do what "lovealwaysnepal" suggest. In addition to that if you wants to send some things then I would suggest you to buy him a electric bed. I forget the exact name of it  but you will find that in walmart. It gives warm as well massage to the back. It  is very helpful to senior people as most of them have back problem at this age. It will cost you below $100. Let us know what you will send them and their reaction.

Peace,

Times
