Discussion: The benefits of orienteering

This article, from a very non-athletic publication, touts the benefits of exercise in preserving/enhancing cognitive capabilities. If dumb exercise is good, orienteering should be particularly effective?

Thoughts?

There was that other Gretchen Reynolds piece about feeding the newly minted orienteers brain cells cocaine. All I say is I stopped being a fan of parallels since the GPS thread.

Great line from latter study: "Afterward, the mice were placed in small multiroom chambers in the lab and introduced to liquid cocaine. They liked it."

The Flying Pig and US Champs supported the thesis that my increased exercise since retirement has improved my cognitive abilities on Fridays and Sundays, but not Saturdays (no focused tests for M-Th yet). Do the mice offer any suggestions for Saturdays? :)

I do like the concluding advice of the latter study:
“Exercise is good for you in almost every way.” But it is wise to bear in mind, he adds, that, by exercising, “you do create a greater capacity to learn, and it’s up to each individual to use that capacity wisely.”

Am I reading it correctly - exercise creates a greater capacity to learn but that capacity is not incorporated in to the brain unless some learning activity takes place?
I think I'll need a marathon run to figure it out.
