A little something about nothing

Question for God

As I laid in bed last night making an attempt to fall asleep I started thinking about my grandpa. It was good thoughts and it made me smile instead of cry. One thing I thought of that I didn't know the answer to is what heaven is like for my grandpa.

At one years old my grandpa went deaf from being sick and his family not having enough money or the doctors having enough experience to help him. I just wonder if now that he is in heaven if he able to hear again or if being deaf is just easier, meaning everyone understands and can communicate back with him??

Then my thought got a little broader. When people with disabilities are taken to heaven does God take away their disabilities? If so, would the people know how to function after living with the disability for so long?
