I haven't had a cold for ages either using less Vit C than you. But I reckon that the prime minister down here sealing the borders up tighter than a crabs arse at 50 fathoms has had a lot to do with that.
Plus I have to wear an N95 mask at work and on the train helps. !!!
Love to get the beers in Kettering in. Haven't been there since we stopped there on the way to a wedding when we had that monsoon of rain in uk in the noughties I think.
