Anyone who has contact with a university will be familiar with the scourge of Fresher flu - the outbreak of coughs, colds & snuffles which follows exposure to a contagious cocktail of germs from all over the country which the new students bring with them along with their fresh faced eagerness to learn
Now that I am a lady of leisure I recognise a similar seasonal epidemic
Half term flu
This attacks in particular the elderly who are exposed to an alien cocktail of underage germs which are suddenly released into the community at the same time as their strength & resistance are diminished by their sudden inability to find a seat, not just on the trains or buses but in any public place. All seats are occupied by young people sprawling everywhere.
I know it is not their fault. They are just programmed to do that by the adolescent brain.
And have you noticed how half term is even worse now that even 3 year olds have to pack their leisure travel into the school holiday breaks?
