How do you think we will validate supercentenarians in the future? Will it be a mix of documents and their social media presence throughout their life (or lack there of)? Let's say 100 years from now, when the very last people born in the 1900s start dying, how will we know whose claims are legitimate? I think this is a interesting question. I think making false longevity claims will be a lot harder in the future because of the internet. What do you think?
