I think most English speakers would agree that the rupture is usually used in medical context or a plumbing! We would not use rupture to describe someone getting injured while playing football. I agree with David K that rupture is usually used to describe something bursting open-- I generally think of pipes or blood vessels-- something that has liquid running through it. When David explains that infidelity ruptures a marriage-- it's like saying his actions 'busted' the marriage. To answer your initial question-- you could say: -He injured himself playing football meaning He injured himself while he was playing football an example of Rupture: -The pressure of pipe was too high and the water pipe ruptured -He died because of a ruptured artery i hope this helps

This made me giggle because English is so ridiculous. I'm so sorry! Most people in the United States would say: -No (you don't have to say, "I don't mind"-- it's implied) -No I don't mind if you sit here -Feel free to take a seat -Nope (you don't have to say, "I don't mind")

On good days implies that the speaker is personally feeling well or confident. For example if a person is chronically sick-- they may have good days, when they feel well....or they may have bad days, when they feel ill. So in this example if someone is saying the speaker is a "fighter and can do it"-- the speaker is implying, when they feel well, they believe it.

I am not sure exactly what you are trying to say. For example-- if John, Mary, and Paul are the same age (23 years old), they would say: "We are the same age"
