Blood-letting and excavations - 2

So far I have spat a lot of spit into a vial, had enough blood taken for 18 samples to be shipped to various centres around Europe (this is an EU research project), had the insides of both cheeks scraped with a toothbrush – orange for right, blue for left – and now, deep joy, I find I have to save all my pee for 24 hours which means I have to decant it all into an orange petrol can and carry it back with me tomorrow. At least I won't have to carry today's output around Westfield on my way home as they're giving me a second petrol can!

I haven’t eaten since 20:00 last evening, my stomach is rumbling and it’s only 09:40 L
