”The number of colds and coughs I've had over the past couple of years has gone right down…I like not having a cold."

Quite so, Kevin. I haven’t had a cold for two years now - my last cold was early January, 2020. I’m persuaded that, along with the reduction in socialising since the start of the pandemic, wearing a mask in public has contributed to my remaining free from colds and/or other respiratory infections.
