I’ve seen people suddenly look younger before, namely an elderly man that was my neighbor when I was young. It was never explained to me, but I’m pretty sure something like dementia or a stroke caused it. He looked at me, curious and delighted like a small child - and I could’ve sworn his eyes were never that blue before. It really freaked me out, but I guess it just means the expression we wear does a lot for how old we’re perceived as.

Well, Snopes said it’s not AI (credit to Tango above) and I don’t believe in the power of blood drinking, so I’m sticking with my theory for now.
