People rollerblade less.

I read that fall injuries in the elderly are a significant contributor to both death and drops in quality of life.

When it comes to proprioception and balance one group of people over 60 seem to have equivalent balance to younger people and that is certain kinds of rollerbladers.

So as a person who was relatively active (40mi+ per week biking and other things) I started rollerblading and it's been unbelievable, I'm older and certain types of movements that take 8yr olds a couple weeks to learn took me nearly a year, it's absolutely amazing though, pain and soreness in parts of my leg and feet all related to stabilization, significantly strengthened stabilization muscles and improved reaction times at speed. I figure if I can rollerblade on one foot at 15 miles an hour, walking with both feet at 3 should be no problem.

I put rollerblading and bouldering as my top two 'puzzle' based activities.
