I’ve been healthy for so many decades that I’ve never thought about it. Until lately, that is. Even though I’ve been careful I wonder each day if my luck will hold out. I’m probably not the only one who frets about this. Tomorrow is promised to no one, especially in these times. But man, what a feeling in the morning when I breathe deeply, taking that living-room air all the way down into the bronchi, bronchiole and alveoli, and I swear to God the lungs feel as clean as they did when I was ten, even though I smoked for 15 years or so. Famous last words, right?
