It's going to be interesting over the next 50 odd years to watch the rise and fall of disease in the world. Most of them will be caused by ourselves with over use of chemicals, radiation, genetic modification and mis-use of medication. I will be glad to see the compulsory introduction of electric vehicles in urban areas and an increase in pedestrian walk throughs etc. But, I am not going to worry myself to sleep tonight over something that may or may not occur. If I go on holiday to the Hawkesbury in Oz could catch a very strange disease, if I take my family to the good old US for a holiday then meningitis is a risk for the kids. Better not go there either, if I go to UK might become a silly old moo, better not go there. If I go to Europe might eat some un-pasteurised stuff and die, better not go there then. OK I'll stay on my porch and have another cold one here. Just watched the sun set and it was beautiful - aaah blissful ignorance what a joy.
