Some look for reasons to feel bad. Example: Why do you celebrate Birthdays. They are to highlight that you just moved older..why do you think about feeling old, like this question and answer. Some look for reasons to feel old. I still believe one of the biggest killer is
STRESS and we do a lot to give ourselves stress. As my 102 year old grandfather said..
"You people worry too much". He had been a sheriff, a farmer,etc and I never remember him being stressed. He had a great "just accept it" as a way of living.
