Well said, everyone.
It's no problem having you younger guys chime in, in fact, it's welcomed. The more inter-generational PK becomes, the better. In fact, ANY endeavor that fosters generational interaction is to be lauded.
Most of my daily physical activity is not made up of PK, but of shooting hoops and bodysurfing. Both activities are greatly enhanced by the generational interaction. On the courts (while I bring in all of my 55+years), most of the guys are in their mid twenties to mid thirties, and out in the surf, you get everyone from 15 to 60+, and it's all great because of it.
The young have their youth to offer for inspiration, while the more "advanced" (as we like to call ourselves) have the wisdom of our years (and injuries) to provide perspective. It's all good. We older guys KNOW (or should) that activities have to be scaled back by degrees, because the older you get, the longer (if completely ever) it takes to heal. So injury-avoidance is a high priority.
There are a lot of basic moves in PK that will greatly enhance how you carry yourself through your environment, without EVER having to pull off anything even remotely dangerous. I've done little seat and rail-hops at the ballpark that have "earned" me some favorable remarks from complete strangers who were sitting next to me, and these were guys who were 20 years younger. If you practice ANY PK moves, your going to be ahead of 99.9% of the entire population of the planet, so it won't take much to set you apart from the crowd.
I've also had some great sessions just playing around on jungle-gym equipment at parks, and rock-hopping on boulder seawalls and jetties at the beach. You just have to be creative and have fun. You younger guys weren't around "back in the day" when I was growing up, but there was maybe one or two kids in any given class who were overweight. Now, it is at least half the class in any school anywhere you go who are overweight, and they are well down the road to encountering a boat-load of trouble by the time they are forty (if they happen to live that long). This current generation is the most unhealthy generation that has ever walked the planet in "modern" times. The chicken is going to come home to roost.
All that said, PK (practiced with reasonable moderation) will help to keep the "wolf at bay", as long as you don't end up in a walker by forty from a dozen broken bones, sprains, strains, tears, bruises, abrasions, concussions, contusions. . .you fill in the blanks.
Be careful, and have fun out there. . .
