After living in Australia for nearly 10 years, I’ve unfortunately only been back to see my family and friends in the UK, a mere three times – and with COVID-19 still at large over there, my chances of a convenient trip home anytime soon look bleak.

All three trips have been for summer weddings – and for two I was best man for friends I’ve known virtually all my life.

Recently, one of these friends sent me a picture of his full blood count – he’d had bloods taken after consulting his GP with mild gastrointestinal symptoms that had started more than several months previously.

The results were alarming for anyone, let alone someone aged just 40.
