How do we know Captain America has an extended lifespan? He was only kept young because he was frozen in ice, and he only survived in the ice because of his healing factor, so that has nothing to do iwth "longevity." And we also don't know at what point in his life he decided to return to the "present," so we don't know that he was actually 120 years old, and even if he was 120 years old, it's still possibe for normal people to live that long, it's just rare.
I've seen edit wars over the article. Deke Shaw's has been protected, and Malick's will be too if people cannot learn to have a little patience and see how the TV series that we cover explains what we cover.
If I may join, we have already established how we are going to work with characters that are alternate versions. We had a discussion already, and how we will proceed. There are changes needed but eventually.
