"Well since I'm staying with you at least you have a sort of doctor nearby if something happens." Bruce was very calm under pressure and it wouldn't be the first time he looked after his friends from injuries. He liked doing that instead of focusing on whatever the Hulk did during a fight. Healing was better. "You have a doctor on call. You can literally just yell my name." He smiled wryly. That's an extra good thing about staying with Tony, outside of the fact he was needy and attached.

"We're old now, pal. We're just ahead of the joints because of all the action." Bruce himself was in worse shape than Tony in general, at least in terms of exercising and fighting. But he'd never really needed to focus on it before. He felt a decade older than his friend and usually a few decades older than everyone else. "I don't have someone healing me now though. So I'd better start stretching, huh?" The Hulk meant that Bruce was the safest and healthiest among them, most of the time. His own blood was radioactive, but that kept anything else from poisoning or hurting him. It wasn't just the physical manifestation of the monster that existed, it was in him down to the cells.

Now it was gone.

"You think almost fifty is too late to learn how to punch without a supersuit?" It was said as a joke, but also not.
