The result of covid is throwing up a number of long term damages. With long covid the loss of smell is one of the side effects. I can hardly imagine not being able to smell as I cook, not to smell the old fashioned rose blooming in my garden or newly baked bread as I walk past the bakery in my high street. Of course, there are unpleasant smells that sufferers are also missing but the pleasant smells are more numerous.
I understand there are now treatments to try to retrain this sense; time will tell how successful they are. This is a sense which we hardly notice until we lose it. We seem to be failing all the time in this way. Old age can affect the sense of smell as well as hay-fever. This is yet another gift of God which we need to appreciate and give thanks for.
