I read Elton John's autobiography over the holidays and loved how he mentioned getting his pacemaker in a positive light, flew to London for surgery then got back to touring.
"I was only in the hospital for one night and, rather than feeling debilitated, I thought the pacemaker was fantastic. It seemed to give me more energy than before."
p.s. this book was AWESOME! Highly recommend.
