The other scientist fixed him with a direct stare, unspeaking for several moments. Then he said: ‘Am I hearing what you’re saying?’

‘It’s a self-defeating ladder, developing stronger antibiotics when resistance makes useless those that already exist. Making cocktails of drugs, a lot of the constituents of which are totally ineffective and can even be harmful, is bad medicine. The logic can only be the build-up of even greater resistance which in turn needs even greater – stronger – antibiotics. It’s happened worldwide with methicillin-resistant staphylococcus aureus. We’re breeding our own superbugs from superbugs, not eradicating anything.’

‘Eradicating?’ picked out Benn, at once.

‘Isn’t eventual eradication the focus of medical science?’ frowned Parnell.

‘ Medical science,’ heavily qualified Benn. ‘Our focus is pharmaceutical research and developing and improving drugs to combat known diseases.’

‘Aren’t they allied?’

‘I suppose that’s a point of view,’ allowed the section director, doubtfully.

‘It’s always been mine.’

‘You haven’t yet been to a company seminar, have you?’ asked Russell Benn.

‘Not yet,’ said Parnell.

‘There’s one soon. You’ll find it interesting.’

‘I am finding this conversation interesting,’ said Parnell, directly. ‘Interesting as well as confusing.’

‘Did you know that years ago tyre manufacturers perfected a tyre that never wears out: if they were fitted to cars and trucks they’d last the lifetime of the vehicle.’

‘No, I didn’t know that,’ encouraged Parnell, who did, but wanted the analogy expanded.

‘Planned obsolescence,’ declared Benn.

‘Yes,’ said Parnell.

‘I think you’re right,’ declared Benn, on another tangent. ‘I think there could be work we could do together.’
