We recently had some beach replenishment performed on local beaches concurrent with a winter that seemed to be a non-stop swell generator. Created, temporarily, pointbreak-like conditions with dredging barrels at lower tides and loooong rippable walls at higher tides. Surfed my brains out a few times a week, sometimes twice a day, up the block and at 42 years old I felt like I was surfing as well as I was when a decade or two younger. Makes me wonder what I could be capable of given a consistent supply of time and surf.
That said, now at 44, I'm starting to suffer from some age-related, wear-and-tear-style ailments (hip, shoulders, etc.) that make me recognize there is certainly a limit to the aforementioned philosophy.
