I’m a dedicated and sometimes not very subtle eavesdropper. When we were travelling on the London Tube a few weeks back, two hipster types were sitting opposite chatting away. Naturally, I listened in.

‘Called the doctor today to get my hands on some Champix. I really need to quit the fags. He asked me if I felt suicidal which I thought was a bit odd. I said no. I’d already had a G and T so I was feeling pretty good. Then he asked me if I felt positive about the future. I laughed. I said as we’re in the middle of a pandemic, with Brexit, more austerity and mass unemployment ahead, I found it hard to be positive. Fair enough, he replied.

I should be getting my pills soon. So, depending on how well I cope with the pandemic, Brexit, more austerity and mass unemployment, I should be smoke-free by 30!’

‘Not at chance,’ his friend replied.
