"Umm, I think it's enjoyable activities in general?"

"...but exercise isn't."

"Well, after you exercise you usually feel nice, that's supposed to be endorphins, I think. ...I should know more about this, biology's my thing."

Shrug.

"Anyway, I do know for a fact that having fun produces hormones that make your body behave better and are good for your health, even if they're not endorphins."

"I dunno that I can really do anything with that advice."

"Well you can still exercise. Like, run, maybe, or swim, or play some sport."

Jackson looks skeptically at Sadde, as though Sadde has suggested that since horses are conventionally understood to be healthy he should turn into a horse despite being a psion.

"What? It's fun! After you exercise you feel all energized and such, I know it starts out boring but it's really not."

"Maybe you do."

"I think it can take up to an hour of exercising before the effect kicks in, usually between half and three-quarters of."

"That's a long time."

"I think it's sorta the standard amount of time for an exercising session? Perhaps for this reason."

"I keep hearing, like, twenty minutes three times a week or something."

"Huh. Maybe I'm wrong, then. It doesn't work at all for me until I hit the thirty-minute mark, though, and only does so reliably after forty. The feeling-really-good-about-myself-after-exercising thing, that is."

"Huh."

"...how about you come with me next time I go exercise?"

Jackson considers this. "When?"

"I dunno, I don't have much of a schedule, we could go today after class? Or tomorrow before lunch, I don't have morning classes at all tomorrow."

"I don't either, I guess that works, you might have to remind me at breakfast though."

"Sure, sounds good."

Jackson manages a little smile.

Ooh! Little smile! That's good! "I usually like to jog or run around town when I do that, you cool with that or do you prefer something else?"

"That sounds okay. I dunno if I can run very fast."

"Doesn't need to be very fast, jogging's good enough."
