SIR - A few years ago two of my work colleagues, having reached their 60th birthdays, were invited to send stool samples to the NHS to determine whether or not they had bowel cancer. In both cases the results came back as positive. There's no doubt that subsequent treatments saved their lives.

I celebrated my 60th birthday a month ago. Am I to assume that my invitation as fallen foul to the Covid-19 hysteria, like many other important procedures?
