77 here, 78 if I make it to June 25. So far, so good! I became "fully vaccinated" in December 2021, but my wife is not vaccinated at all. My pulmonologist scared me into getting "jabbed" because of my co-morbidities of heart failure, type 2 diabetes, and age. He said if I got a COVID-19 infection that I would surely die! Well, I don't want that to happen any time soon, so I got jabbed. No effect. No "flu-like" symptoms, no headaches, no muscle soreness. Nada. I may have already developed self-immunity from previous exposure to the virus or a similar variant of it, but have not tested positive for COVID. I was tested prior to having my heart pacemaker/defibrillator replaced last year with a better, smaller, three-lead instead of the former two-lead, device. New lithium-ion battery, too, good for perhaps another ten years... I wonder if my wife can get a refund if I expire before the battery? Nah, someone will probably remove and re-cycle it...
