It's got nothing to do with luck. Having a healthy lifestyle plays an important role in not getting ill. I eat good, nutritious home made food, I regularly exercise, get plenty of sleep, don't smoke and hardly drink alcohol at all for the last few years. If I catch a bug, I can usually shake it off quite quickly.
What offends me are folk saying people like me who don't want a Covid vaccination, should forgo medical treatment, when I've looked after myself all my life, and paid taxes for 20 years. There's plenty of people out there that abuse and neglect their bodies every day. The amount of people I see in supermarkets with trolleys piled high with fizzy drinks, junk food and alcohol, is scandalous. But it's their choice, just how I don't want a vaccine.
