Covid testing

We received a letter several weeks ago asking us to take part in a Covid research study to estimate the prevalence of Covid in the community. I agreed to take part a while ago and rather thought I was not needed as the weeks passed. However , last night I got a call and today after a chat to a nurse over the phone Covid swabs were delivered to our doorstep and the Chief did the needful for me. Results should be back in a couple of days (I feel completely fine). And yes the nasal swab was uncomfortable.
