Unless your windsurfing has become static and not progressing, no 'magic' board remains so indefinitely! It's just the memories that linger. (which is a good thing )

I still retain (hoard?) many (all?) of my old 'Magic' boards, but when I get on them again now, which I do from time to time for nostalgia, I can definitely tell that my perception of 'magic' has evolved. My current, newer 'Magic' boards are possessed with significantly more 'Magic' than those older ones.

And, somewhat surprisingly, they make me feel like I am a much better windsurfer than I probably really am. LOL!

Moral: 'Magic" is fleeting'. Live in the moment, not the past.
