I don't believe in luck. I will be 67 next year and always had a great immune system. I did get the flu in October for the very first time. It was not Covid because I got tested the week after I was fine. As an aside, I can still get it up without any drugs. I attribute this by working out 5 to 6 days a week at my local gym. and eating healthier. I never smoked, drink wine occasionally with my meal and don't do drugs. I don't look my age (younger) because I can pass for a man in his mid fifties. I have very good genetics. I believe when your time is up, then it is up. I don't live in fear.
