Since my legs have begun to fail me, I have been swimming laps every morning. My friend Carl Trop suggested I get a FINIS DUO, underwater head set. He let me try one of his. It was life changing. I bought one and now every morning, I have these speakers sitting on my cheekbones attached to my swim goggles. I have been listening to Neil deGrasse Tyson’s book “Astrophysics for People in a Hurry” while swimming which eases the boredom of the line at the bottom of the pool I follow. Anyone who swims for exercise should try one.
