Hi Torben, I think what you are doing is just great and just right, I too am about to turn 63 being a 1949 baby, I started surfing in 1958 and the longer I surf the more I believe in whatever gets you in and surfing is the way to go.
A surf movie I recommend for our vintage is a documentary called Surfing for Life with guys who were my heros when I was growing up in the surfing world they were and still are older than you or me and some are still alive and surfing.
There is also a website: http://www.surfingforlife.com
Recommended viewing for all surfers old (cause we just do it) and young (cause we developed the stuff you doing now)
Also try "Going Vertical" . Historical medium old farts arguing over what was each others contribution to the evolution of short boards.
BTW a number of my similar vintaged friends have taken to the pop up struggle by reverting to kneeboards and getting better and deeper quality surf
They're loving it.
Have you noticed that you are more alive, with better reaction time and better all round body functions than your similarly aged contemporaries
Just an edit to add to this the is a thread for late in life beginners here too!
Have a look viewtopic.php?f=6&t=17676
I've taken up troll hunting just for fun, instead of a rifle I'll just use a pun!
