Not everyone can afford to ignore the fact that catching covid could be life threatening. I'm cautious not just for my own sake but the 2 people that I spend most of my time with over here are both very vulnerable to being badly affected by covid's symptoms.
My daughter, who is 45, had cancer 3 times in her thirties, twice with women's problems and the third time lung cancer, and she can not afford to be exposed to covid. The wards of The Freeman and The Queen Elizabeth hospital became very familiar to us 10 or so years ago, and I'll do what I can to keep her safe.
Her fiancé had a Pulmonary Embolism this time last year. His family has a history of DVT and it wasn't a nice thing to see a big healthy bloke fighting to breathe. He just had the all clear 2 weeks ago and the last of the blood clots have finally dissipated, so he also can't afford to contract covid. These are the reasons why I will do what I can to stay covid free.
What is silly about wearing disposable gloves? I put a pair on and smother them with hand sanitiser so I feel more comfortable when handling goods in a supermarket, and when I've finished I remove them and sanitise my hands again. Might seem silly to you, but I simply can't afford to get infected and every step that I take lessens that possibility. Not everybody's circumstances are the same.
