Being in motion.
Preferably out of doors, under the wide open sky (and the stars), with space all around him.
On second thought, make that of necessity out of doors in the good old-fashioned fresh air. Charlie used sometimes to pedal on an exercise bike at his former school. He sometimes liked it a lot and other times he, well, didn't. We have tried him a few times on a treadmill and Charlie's wanted to get off fairly quickly. I'm wondering if he just doesn't see the point of doing repetitive movements on a noisy machine, of pedaling and pedaling and not--so unlike on his bike---getting anywhere?
I have to admit, I am with him on this. I've been running since being on my (very small) high school's (quite small) cross country team. I've been always run outdoors (and in some inclement weather), except for a couple of months when I became a regular at our local fitness center, on the treadmill. I'd rather have scenery to look at, instead of TV monitors and the numbers for 'distance covered' and 'calories burned,' not to mention all the clanking and dials and buttons.
Though thanks to Charlie lately, I haven't been bothering with morning jogs. Thursday was another 6-walk (one a long walk), bike ride day, plus Charlie again woke up way too early. There's an intense amount of energy (as you may gather) in our boy and he seems to have figured out what to do with it:
Get into motion.
It does make me think that it's going to be a long, long while before Charlie can sit on a cross-country airplane ride. In the meantime, we'll be walking.
