I'm 38. I plan to retire when I'm around 52-54. Once retired I will have way more time to dedicate to chasing swells. What I worry about is that maybe by that age I will be an old cripple and won't want to hit waves daily. Already, after a long session my lower back aches and so does my achilles tendon on my rigth heel! WTF? How old is the oldest surfer you know?
