Hell ya, not only taking a correction well, but coming back with extra information to correct the original misconception. You seem like a cool person, thanks for that!

The incredibles touch on this. Mr incredible needs to get back in shape which implies he had to work out while being a super hero.

You already got your answer but I just wanted to say good on you. Not too many people are willing to recognize they made a mistake and try to improve. So assuming this is good faith, thanks for being a good person!
