FaceApp: How accurate are the predictions?

I mean- face apps can’t really predict plastic surgery or lifestyle even if they did use some really complex algorithm. Generally people tend to age in certain ways. The nose and ears get bigger, certain types of wrinkles are common to most people- but some fave shapes get certain ones more. Then there’s wether you keep your teeth or not. The jaw bone thins when there aren’t teeth in it which can change the jawline and face shape. There are also surgeries for that as well.

Yeah, Dolly had a shitload of work done so it makes sense she looks nothing like it, and Attenborough just went a totally different way. What I'd love to see is someone do young Tom Cruise, then faceapp him, then show him now looking younger than the faceapp
