Piss funny pisstake, of course, but not too much of an exaggeration. I particularly like his description of his white blood cells. My idea exactly, except that with my huge proclivity for canine friends, I call them my ‘Big White Dogs’, after the sterling family of breeds developed so effectively over the past few thousand years to be formidable - and formidably intelligent and effective - flock guardians, 24/7/365and1/4. Literally never off-duty thoughout their lives. I have spoken with shepherds in Turkey who have kept flocks in wolf-territory mountains for many years, with never a sheep or goat lost to predators in all that time. Serious dogs! I like white blood cells of that quality, and always keep lots of them on hand, and - crucially - fed always with everything they need. Maintenance of a truly beefy immune system: the only thing, in the end, that keeps us healthy in the face of all the pathogens permanently present in the all-encompassing air plankton.
The only thing George misses out is vitamins, particularly C. I presume he would have found such supplementing to be pussy stuff!
