If You're 100 Years Old Then I have Some Questions For You

If I met someone that was 100 years old and was still able to answer some questions, these are the few things i would ask them. Of course they have a lot of stories from their long life but i would want to know the one thing they remember the most. I would also ask what was their happiest memory and then i would want to know if they had any advice for me. i recently visited my great grandma who is 90-something but i didn't ask her much. She had one good ear that you had to scream into if you wanted to be heard, so our conversations didn't last long. But if i did meet a 100 year old person that would answer me, then i would definitely ask.
