About 10 years ago, my doctor told me I had 98% closure in both ears and he recommended surgery to clear the calcium and to help prevent future ear infections. After he explained the procedure, I chickened out and decided to try Doc's earplugs instead. They are available at most surf shops for about $12 in small, medium, large and extra large-with a leash or without. One of the good things about them is that they offer a "vented" version which makes it easy to hear sounds around you. About once a year, I still get excruciating ear infections, but they seem to go away after a few days. I'm now 56 and wouldn't surf (expecially in the cold winter water) without them. Hindsite is 20/20. Wish I would have flossed more too.
