Applies to many of us (unfortunately).
I like explanations.
Yep, old people living with pain can be a bit grumpy some times. No need to spend a lot of money on research , just ask my wife. Is there anyone out there that thinks that any body living with pain would not get a bit fed up ,argumentative, self centered and have almost no patience with others. Sometimes you have to force yourself to consider others and be a little more civil to your family and friends because it is not not their fault. I do yell at the really stupid people on TV. That does not do much harm, well unless there are others watching with you.
