Although Captain America is often described as not being superhuman, he can clearly survive things that a regular human wouldn't, such as being frozen in ice for seventy years.
I'd like to understand how severe of an injury he can survive.
For that, I'd like two details:
- What is the worst physical injury Captain America has ever recovered from? Has he ever lost a limb or organ, or broken a bone?
- If he's ever died, what was needed to kill him?
I'm not limiting this to any particular continuity, as long as it's an official Marvel property.
