this could happen due the sister moving faster than closer to the speed of light relative to her brother.

edited: correcting theoretical error. Thanks to pearsaltchocolatebar@discuss.online for pointing that out.

Or if the sister died.

Not faster than, just closer to it than the older sibling.

I've seen this one before in a popular YouTube video that was going round of a builder springing this one on his poor mate who fell for it and after everyone started laughing at him still couldn't figure it out and still couldn't after being given a second chance and still.didn't understand when it was explained to him through steiffked giggling.

I didn't understand it then until embarrassingly late in to the video and felt bad for the poor guy who obviously cops that shit from his 'friend' a lot so the memory and details of it really stuck with me.

I saw this post, saw the title read the first part of the setup, knew something was coming and still fucking guessed 35 and although I knew that that was the trick answer that this is rigged to elicit and knew that I was wrong I still couldn't figure it out for like several seconds. Something about this pretty simple trick is remarkably effective at short circuiting my brain even when I know the correct answer.

"Wrong. That sister is a decoy. I tell her to meet me in Mexico, but I go to Canada. I don't trust her. Besides, I like the cold. Thirty years later, I get a postcard. I have a son and he's the chief of police. This is where the story gets interesting. I tell Tiffany to meet me in Paris by the Trocadero. She's been waiting for me all these years. She's never taken another lover. I don't care. I don't show up. I go to Berlin. That's where I stashed the chandelier. "

Not enough info to say for sure, but between 66½ and a day before 68 years old. It depends on when during the age of 6 the sister was exactly half the age. The sister is between 3-3½ years younger and we don’t know exactly where during the older sibling’s 70th year the question is posed.
