This possibly dates back to times of chivalry. Men were supposedly to be kinder and more respectful to women. I couldn't imagine being on a sinking ship and not allowing children to safety first. I'll admit that feminism can be a pain sometimes but when you read some of the responses to it one can easily understand why there's a need for such a thing.
Inversely though, I see women all the time stating that things such as taking out the trash and mowing the lawn is "man's work". We all have those funny little qualms. I think acts of strength (heavy lifting) is something men should do simply because we can be hurt by it and as a man I'd prefer I be hurt than my wife. However, my wife loves to prove that she can do anything I can do. I love giving her a shot and laughing (in my head) if she fails lol.
