Appreciate the sentiment, but gotta admit that I feel like I am still pretty far from this achievement. I suspect that balance is a goal that will remain perpetually just out of reach, and I am fine with continuing to work on it! To that point, I started skateboarding last week in an effort to improve balance. Rodney Mullen is my new hero.

I would recommend slack-lining as well if you are looking to improve balance. I also think it is safer than skateboarding too in terms of joint health and all of that.

I have a slack-line but get very little opportunity to use it. I'll start keeping it in the vehicle so I can bring it on kayak expeditions–adequate clothes-line and camp couch–and on the off chance I find a spot to use it.

I am looking to increase the impact, not reduce it. I know that I need more bone-rattling in my life and can't justify the purchase of a Juvent. Skateboarding provides benefits similar to that of a Juvent, plus I might learn how to fall (and skate).

Since you seem to like snow sports, you should perhaps try downhill longboarding.
