Stubborn about Fighting Cancer for Extended Lifespan and Healthspan

 This morning Melissa and I exercise-walked north from our house  along NW 27th terrace..then turned around and walked back home.  i'm not happy that this walking of mine for distance is such a tiring grind, remembering how easy it used to be: I want to go back to being a power walker, challenging the 40-minute mark for 5K's.With slow running I want to be like Ralph the Ageless Runner on YouTube..I love his shows.As for me, I strongly want to become confident in my proven ability to slowly runfor long distances as I live through this unwelcome era of sudden cancer diagnosis bombs dropping on me and disrupting my life, physical mobility and hopes for my future as I want to live on a high-functioning level throughout my seventies..and possibly deeply into my eighties..The marker of my level of stubbornness that I embrace, without self-shaming, on the present moments of my immediate physical environment, is  and should be a highpriority for me, and for you...
