Correction: Just curious, because a friend of mine dared an old man and the old man accepted the challenge and after he did it he was hospitalized. I wouldn't do the challenge myself because I think it's silly, but yes, I would dare an older person if they looked like they'd be able to do the challenge. Someone who is obviously frail or infirm is a different story.

Hmmm I honestly don't know. I probably would but just like what Andi mentioned, if the man is sickly then I wouldn't it.
