Say, for example, there was an apocalypse booked in for next Tuesday. Would it wipe out the entire globe, or just half of Kilmarnock (not the good half, obviously)? We simply do not know. Would cheese be available, in either respect? I think it is quite likely that some foodstuffs might survive, and that cheese might very well be among them.
Especially the hard kind, such as Parmesan.
Would we be able to buy it? Only if money and a trading environment survived. Money and buying might be consigned to the dustbins of history, post-apocalypse. We might have to stoop to 'looting' it.
As for 'enjoying' it - well, stolen fruits and all that. And it would all depend on a decent cheddar being available. And on not impairing one's enjoyment of said cheddar by worrying about skyrocketing cholesterol.
I'm bored thinking about it now, and am moving on to 'what if the whole world went underwater due to apocalyptic flooding and to escape Kevin Costner - how quickly would we develop gills?'
