For surfers, the ocean is a powerful magnet that keeps luring them back.
That's certainly the case with 68-year-old Ron Greene. Four times over the past 14 years, Greene has suffered heart attacks while surfing. Yet, he keeps surfing.
"Maybe I'm an idiot. Maybe I'm a fool," the affable Greene said. "I just want to keep living and enjoying it. There is an immensely good feeling after surfing. … I force myself to go out there sometimes just for the exercise and the feeling afterwards.
"Believe me, now that I'm older, I don't like surfing crap. I like to go out when the conditions are nice. But sometimes, you just have to go."
Greene, who has owned a San Diego auto storage business for 45 years, can recount his heart attacks with little emotion and great clarity.
He suffered his first at age 54.
"I got there with friends and I wasn't feeling too good," Greene said. "I paddle out and there's a nice little set, and then — boom! — it's like an elephant is sitting on your chest. It's super-painful."
Greene managed to paddle to shore, called his doctor and drove himself to the hospital. He went into surgery the next day to receive seven stents. On the table, he said, he suffered cardiac arrest.
