I think age is not a number. It's the weight of responcibilities you start getting on your shoulders. As you progress through life. So the simpler your life, less weigh'd down you are -- the younger you feel and look and think.
My kiting progress has been much slower then my progress 10 years ago while picking up windsurfing.
Age might be a factor. But a decade ago there were no responsibilities, no wife, no kid, no mortgage .....nothing. Just top of the line windsurfing gear always in the car. Always ready to be rigged up.
Now with all the above, difficult to consistently get out. Biggest single factor is having little kids. They just tire you and make you feel 58 instead of 38. Specially the one's which don't sleep well at all at night.
Dude,,,,I totally relate... I am 51 now. My two boys are 18 and 22. As they grew I built them every kind of skateboard ramp and funboxes and whatever they were good at I fed into a...We snowboarded all the time but being from Florida we prefer warm vs cold.
Now we all kite all over. Brazil, DR, Mex, Costa Rica, Keys. Life doesn't get any better....I split up from their Mom about 5 years ago...but my relationship with my sons is second to none...thanks to Kiting...Your kids will grow and although you wont' throw it down like years back...you will always shred for years to come and your kids and family all benefit in the end....I mean...how can you not want to kite???? Dad does it!!! Wait till you can kite with you kid and high five on the waves off Paracuru at Thankgiving!! dont get no betta!!
