* He had a recurring ear infection: This was a minor but persistent problem that required treatment.

It's important to note that:
* There's no evidence of major medical issues: The rumors about Hathaway's hospitalizations being due to serious illness are unfounded.
* He recovered fully: Hathaway went on to have a successful career as an actor and later as a stuntman.
