Just looked at the 1919-20 season at the height of the Spanish flu epidemic that killed more than died in the first world war, we played man united at meadow lane attendance 35000, every home game crowds over 10,000 , away games Birmingham 30,000 Liverpool and Villa 35000, and not one fixture cancelled.
what a bunch of wusses we've turned into nowadays, the programme seller gets a sniffle and off the lot goes!, then again back 100 years ago, i suppose when you've just return from a war, survived the trenches of the Somme and constant death and shelling on a daily basis, a virus with a risk factor of 1 in 173 of killing you , that's not going to bother you.
