Just as you said, I understand your perspective as well. I realize that I am fortunate indeed not to have major illnesses with which to grapple. I give credit to my many years of race walking. Even though I had a full-time job and a family, I made time to do this because I enjoyed it. After retirement I switched to walking because I no longer had a track available. My husband died 2-1/2 years ago after a 62 years old relationship. I am still not close to be over that. Shortly thereafter I had to have a hip replacement. Perhaps the race walking wore it out. And yet I am still here with my mind intact which enables me to live independently. I will be 90 in less than six months. How much longer? Who knows. In the meantime I just go on. I hope you get better or else get better at coping.
