Itachi nodded. He'd actually grown up to be remarkable tall for someone with a congenital heart defect. Iatchi looked at his hands. "I'm not actually sure it's related to anything now. I hardly have a murmur and I know it effects my stamina, but I've learned to work around that." Itachi paused.

"I don't know that any of this is related, but it seems too coincidental." Itachi didn't believe in coincidences. He believed in patterns. "I've begun to...notice some things." Itachi made a hand motion and sat back. He was committed to telling Obito. Now he had to make it sound as trivial as possible.

"It's small things. I check more colds than I used to and it takes me longer to get over them, mostly. Travelling from area to area naturally means I run into a wider variety if illnesses and am more likely to catch things anyway." Itachi watched Obito carefully as he spoke.
