A couple things that have really helped me lately are prone ups/Cobra (like a push up but you stay in contact with the floor from the waist down) and another stretch where you lay flat on your back and throw one leg over. Both were recommended by the PT to help stretch my lower back and they, along with some strengthening exercises, have made a big difference for me in keeping my lower back from aching toward the end of runs.

Doesn't answer your question directly but those short lint fibers can be pushed into a toilet paper roll and made into firestarters that work at the campsite

Was it a whisper?

Perhaps 'twas not heard, but seen.

Hope the shorts made it.

I have had much better luck using a cup to trap them. Seems to me that they aren't as likely to fly away when I approach slowly with a cup to trap them inside the cup, then slide a piece of paper or cardboard across the opening and release them outside. Of course only works when they land on a flat surface like a window.

I've been on Pandora for a long time now and, as someone above said, I enjoy the "radio" aspect of it to discover new music.

That, and isn't Joe Rogan on the Spotify payroll?
