When Jeremiah McDonald was 12 years old, he recorded a message for his future self. In the video, he fired off a list questions and twenty years later, Jeremiah (now a filmmaker) sat down to answer them.
Jeremiah turned the two videos into a clip called â€˜A conversation with my 12-year-old selfâ€™ and the result â€“ his 12-year-old self interviewing his 32-year-old self â€“ is really quite amazing.
Itâ€™s notched up more than 4 million views since it was loaded to YouTube last week. Youâ€™ll see why.
So, if you could go back and ask your adult-self a question, what would it be?
