Losing teeth is no problem. It is the bacteria growing between teeth are the ones which will attack the heart.
My biggest joy at age 81 is need zero prescriptions, have zero pains anywhere in my 5’-8” body weighing 155 lbs, and looking to join a ballet dance class without getting laughed out of class. It is such a joy to have a spring in the steps and have the balance of a ballet dancer. It was not that way at age 55. I was a basket case of physical issues, then.
More power to you! I’ll match your age in June..but apparently not your vigor! Too many miles on the old legs and wear and tear in general here. Was doing Senior Olympics until 2018. Despite all I still look okay..especially since I’ve been losing weight on purpose. Godspeed!😀
