"The thing described attractive and repulsive forces. I want to see if I can use that as a sort of telekinesis, long term, or just throw things around short term. Gravity and anti-gravity."

"Might work on magnetism too."

"Aren't those different forces?"

"Yes, but it's the first thing that comes to mind if someone says 'attractive and repulsive forces', antigravity isn't the sort of thing you find in nature."

"Maybe. I'd been thinking of it more generally. Still, we can test all of those."

"Doing stuff with magnets probably synergizes with lightning eventually."

"Might give me an easier time of it, at least."

"You think the affinity works in that direction?"

"My affinity's for fire. I'm just stubborn."

"Oh, I see. Not a fire fan?"

"It's not as useful, and my affinity's weak anyways."

"They come in strengths?"

"It's - how easy you find it. Some people find them all about the same amount of easy, just one's a little bit easier. Some find all but one impossible."

"Huh. I haven't tried any elemental techniques at all yet."

"More of them are martial. You'd probably find earth or water most useful. Lightning has a few niche medical applications, though."

"Nerve stuff?"

"Yeah, and I think you can use it like a pace-maker or defibrillator? You need really good control for either, but you need good control for all medical techniques anyways."

"I'd expect so!"

"'Training medics' would be a huge thing to do with a later graduation, especially if we include medical information learned from your universe. A prodigy with perfect chakra control would be lucky to get to professional status in three or four years in the current system, without things like missions getting in the way."

"I mean, in my universe that would still be really fast for med school."

"We probably take fewer breaks."

"Maybe, though all the stereotypes about human med students would have you believe their circulatory systems are full of coffee."

"I've never known a medic who'd admit to sleeping."

"There are occasional very bitter flareups of controversy about whether it's better to have medical professionals work long shifts to reduce handoffs, or short shifts to make sure they're rested."

"We go for long shifts, but shinobi do better skipping sleep than civilians."
