Hey Brandon! Now it was on me to miss replying to your comment...1:1 haha
You hit the nail: these precious lungs - beside the heart - are quite valuable, so we should do whatever it takes to maintain them in best shape.
Sports is great in any sense, and I'm pretty sure it also helps to improve one's lung capacity. I'm still in my recovery mode but once I'm back at 100%, I'll be surfing as if there was no tomorrow :-))
Stay healthy.
Much love back!
