How are your lungs?

If you've smoked, you're never going to have the same lung function as if you had not smoked.

Giving up smoking certainly delivers real, measurable, and immediate benefit, but there will always be lasting and permanent damage. How much damage depends on how much was smoked.

The lungs are like sponges - Smoking turns them into coarser sponges.

I had a go at Swains Lane for the first time yesterday and immediately developed some sort of mucousy cough. I gave up smoking about two years ago but I'm wondering if there's still shit in the bottom of my lungs as that is probably the most extreme workout they've had since...
