It doesn't do to get too precious about catching the inevitable bugs the DGCs bring. Hugs needn't spread germs anyway and I would put up with any coughs and sneezes as the price for little arms flung round my neck! Never ever turn away from a tiny-how do you think they must feel? Hugs can be perfectly safe.
As for sneezes in the supermarket, I agree people can be very inconsiderate but all I can say is your reactions must be quicker than mine.
I wonder if our diminishing immune system might not merely be connected with ageing but because we may be mixing with fewer people. As a Secondary teacher I stayed immune to many assorted bugs from less than scrupulous teenagers but since retiring I seem to catch things more easily.
