Woah!!!! Your grandma does all that at seventy three years old. She walks 3-4 miles everyday!!!! My grandma suffers from tons of chronic pain and she is sixty-seven. I didn't realize he fact that if as a child, you have a certain view of pain, you will have that same view and response as an adult. Like my granddad two years ago had very bad bone spurs on his spine that prevented him from laying on his back for a long period of time. To this day he still has to make trips to Birmingham for a special doctor because of his Parkinson's , also he can't walked on his own , he uses a wheelchair and a walker.
